+# MinGW core-glu makefile updated for Mesa 7.0
+#
+#  Updated : by Heromyth, on 2007-7-21
+#  Email   : zxpmyth@yahoo.com.cn
+#  Bugs    : 1) All the default settings work fine. But the setting X86=1 can't work. 
+#            The others havn't been tested yet.
+#            2) The generated DLLs are *not* compatible with the ones built
+#            with the other compilers like VC8, especially for GLUT. 
+#            3) Although more tests are needed, it can be used individually!
+
+#
+#  Available options:
+#
+#    Environment variables:
+#	CFLAGS
+#
+#	GLIDE		path to Glide3 SDK; used with FX.
+#			default = $(TOP)/glide3
+#	FX=1		build for 3dfx Glide3. Note that this disables
+#			compilation of most WMesa code and requires fxMesa.
+#			As a consequence, you'll need the Win32 Glide3
+#			library to build any application.
+#			default = no
+#	ICD=1		build the installable client driver interface
+#			(windows opengl driver interface)
+#			default = no
+#	X86=1		optimize for x86 (if possible, use MMX, SSE, 3DNow).
+#			default = no
+#
+#    Targets:
+#	all:		build GL
+#	clean:		remove object files

+;DESCRIPTION 'Mesa GLU (OpenGL work-alike) for Win32'
+VERSION 5.1
+;
+; Module definition file for GLU (GLU32.DLL)
+;
+; Note: The GLU functions use the STDCALL
+; function calling convention.  Microsoft's
+; GLU32 uses this convention and so must the
+; Mesa GLU32 so that the Mesa DLL can be used
+; as a drop-in replacement.
+;
+; The linker exports STDCALL entry points with
+; 'decorated' names; e.g., _glBegin@0, where the
+; trailing number is the number of bytes of 
+; parameter data pushed onto the stack.  The
+; callee is responsible for popping this data
+; off the stack, usually via a RETF n instruction.
+;
+; However, the Microsoft GLU32.DLL does not export
+; the decorated names, even though the calling convention
+; is STDCALL.  So, this module definition file is
+; needed to force the Mesa GLU32.DLL to export the
+; symbols in the same manner as the Microsoft DLL.
+; Were it not for this problem, this file would not
+; be needed (for the glu* functions) since the entry
+; points are compiled with dllexport declspec.
+;

+ * A polygon is Y-monotone if the boundary can be split into two polygon chains
+ *A and B such that each chain is Y-monotonic that is the intersection of any
+ *horizontal line intersects each chain has at most one connected componenets
+ * (empty, single point or a single line).
+ * 
+ * A vertex is a cusp if both its ajacent vertices are either at or above v, 
+ *or both at or below v. In addition, at least one of the ajacent verteces is
+ *strictly below or above v. 
+ * A vertex is a relex vertex if the internals angle is strictly greater than 
+ *180. In other words, if the the signed area is negative:
+ *(x1, y1), (x2, y2), (x3, y3) are the three vertices along a polygon, the 
+ *order is such that left hand side is inside the polygon. Then (x2,y2) is
+ *reflex if: 
+ *  (x2-x1, y2-y1) cross (x3-x1, y3-y1) <0.
+ *A vertex is an interior cusp if it is a cusp and a reflex.
+ *A vertex is an exterior cusp if it is a cusp but not a reflex.

+
+General Polygon Tesselation
+---------------------------
+
+  This note describes a tesselator for polygons consisting of one or
+  more closed contours.  It is backward-compatible with the current
+  OpenGL Utilities tesselator, and is intended to replace it.  Here is
+  a summary of the major differences:
+
+   - input contours can be intersecting, self-intersecting, or degenerate.
+  
+   - supports a choice of several winding rules for determining which parts
+     of the polygon are on the "interior".  This makes it possible to do
+     CSG operations on polygons.
+  
+   - boundary extraction: instead of tesselating the polygon, returns a
+     set of closed contours which separate the interior from the exterior.
+  
+   - returns the output as a small number of triangle fans and strips,
+     rather than a list of independent triangles (when possible).
+  
+   - output is available as an explicit mesh (a quad-edge structure),
+     in addition to the normal callback interface.
+  
+   - the algorithm used is extremely robust.
+
+
+The interface
+-------------
+
+  The tesselator state is maintained in a "tesselator object".
+  These are allocated and destroyed using
+
+     GLUtesselator *gluNewTess( void );
+     void gluDeleteTess( GLUtesselator *tess );
+
+  Several tesselator objects may be used simultaneously.
+
+  Inputs
+  ------
+  
+  The input contours are specified with the following routines:
+
+     void gluTessBeginPolygon( GLUtesselator *tess );
+     void gluTessBeginContour( GLUtesselator *tess );
+     void gluTessVertex( GLUtesselator *tess, GLUcoord coords[3], void *data );
+     void gluTessEndContour( GLUtesselator *tess );
+     void gluTessEndPolygon( GLUtesselator *tess );
+
+  Within each BeginPolygon/EndPolygon pair, there can be zero or more
+  calls to BeginContour/EndContour.  Within each contour, there are zero
+  or more calls to gluTessVertex().  The vertices specify a closed
+  contour (the last vertex of each contour is automatically linked to
+  the first).
+
+  "coords" give the coordinates of the vertex in 3-space.  For useful
+  results, all vertices should lie in some plane, since the vertices
+  are projected onto a plane before tesselation.  "data" is a pointer
+  to a user-defined vertex structure, which typically contains other
+  information such as color, texture coordinates, normal, etc.  It is
+  used to refer to the vertex during rendering.
+
+  The library can be compiled in single- or double-precision; the type
+  GLUcoord represents either "float" or "double" accordingly.  The GLU
+  version will be available in double-precision only.  Compile with
+  GLU_TESS_API_FLOAT defined to get the single-precision version.
+
+  When EndPolygon is called, the tesselation algorithm determines
+  which regions are interior to the given contours, according to one
+  of several "winding rules" described below.  The interior regions
+  are then tesselated, and the output is provided as callbacks.
+
+
+  Rendering Callbacks
+  -------------------
+
+  Callbacks are specified by the client using
+
+     void gluTessCallback( GLUtesselator *tess, GLenum which, void (*fn)());
+
+  If "fn" is NULL, any previously defined callback is discarded.
+  
+  The callbacks used to provide output are:	/* which == */
+
+     void begin( GLenum type );			/* GLU_TESS_BEGIN */
+     void edgeFlag( GLboolean flag );		/* GLU_TESS_EDGE_FLAG */
+     void vertex( void *data );			/* GLU_TESS_VERTEX */
+     void end( void );				/* GLU_TESS_END */
+
+  Any of the callbacks may be left undefined; if so, the corresponding
+  information will not be supplied during rendering.
+
+  The "begin" callback indicates the start of a primitive; type is one
+  of GL_TRIANGLE_STRIP, GL_TRIANGLE_FAN, or GL_TRIANGLES (but see the
+  notes on "boundary extraction" below).
+  
+  It is followed by any number of "vertex" callbacks, which supply the
+  vertices in the same order as expected by the corresponding glBegin()
+  call.  After the last vertex of a given primitive, there is a callback
+  to "end".
+
+  If the "edgeFlag" callback is provided, no triangle fans or strips
+  will be used.  When edgeFlag is called, if "flag" is GL_TRUE then each
+  vertex which follows begins an edge which lies on the polygon boundary
+  (ie. an edge which separates an interior region from an exterior one).
+  If "flag" is GL_FALSE, each vertex which follows begins an edge which lies
+  in the polygon interior.  "edgeFlag" will be called before the first
+  call to "vertex".
+
+  Other Callbacks
+  ---------------
+
+   void mesh( GLUmesh *mesh );			/* GLU_TESS_MESH */
+
+   - Returns an explicit mesh, represented using the quad-edge structure
+     (Guibas/Stolfi '85).  Other implementations of this interface might
+     use a different mesh structure, so this is available only only as an
+     SGI extension.  When the mesh is no longer needed, it should be freed
+     using
+
+	void gluDeleteMesh( GLUmesh *mesh );
+
+     There is a brief description of this data structure in the include
+     file "mesh.h".  For the full details, see L. Guibas and J. Stolfi,
+     Primitives for the manipulation of general subdivisions and the
+     computation of Voronoi diagrams, ACM Transactions on Graphics,
+     4(2):74-123, April 1985.  For an introduction, see the course notes
+     for CS348a, "Mathematical Foundations of Computer Graphics",
+     available at the Stanford bookstore (and taught during the fall
+     quarter).
+
+   void error( GLenum errno );			/* GLU_TESS_ERROR */
+
+   - errno is one of	GLU_TESS_MISSING_BEGIN_POLYGON,
+			GLU_TESS_MISSING_END_POLYGON,
+			GLU_TESS_MISSING_BEGIN_CONTOUR,
+			GLU_TESS_MISSING_END_CONTOUR,
+			GLU_TESS_COORD_TOO_LARGE,
+			GLU_TESS_NEED_COMBINE_CALLBACK
+
+     The first four are obvious.  The interface recovers from these
+     errors by inserting the missing call(s).
+  
+     GLU_TESS_COORD_TOO_LARGE says that some vertex coordinate exceeded
+     the predefined constant GLU_TESS_MAX_COORD in absolute value, and
+     that the value has been clamped.  (Coordinate values must be small
+     enough so that two can be multiplied together without overflow.)
+
+     GLU_TESS_NEED_COMBINE_CALLBACK says that the algorithm detected an
+     intersection between two edges in the input data, and the "combine"
+     callback (below) was not provided.  No output will be generated.
+
+
+   void combine( GLUcoord coords[3], void *data[4],	/* GLU_TESS_COMBINE */
+		 GLUcoord weight[4], void **outData );
+
+   - When the algorithm detects an intersection, or wishes to merge
+     features, it needs to create a new vertex.  The vertex is defined
+     as a linear combination of up to 4 existing vertices, referenced
+     by data[0..3].  The coefficients of the linear combination are
+     given by weight[0..3]; these weights always sum to 1.0.  All vertex
+     pointers are valid even when some of the weights are zero.
+     "coords" gives the location of the new vertex.
+
+     The user must allocate another vertex, interpolate parameters
+     using "data" and "weights", and return the new vertex pointer in
+     "outData".  This handle is supplied during rendering callbacks.
+     For example, if the polygon lies in an arbitrary plane in 3-space,
+     and we associate a color with each vertex, the combine callback might
+     look like this:
+    
+     void myCombine( GLUcoord coords[3], VERTEX *d[4],
+                     GLUcoord w[4], VERTEX **dataOut )
+     {
+        VERTEX *new = new_vertex();
+       
+        new->x = coords[0];
+        new->y = coords[1];
+        new->z = coords[2];
+        new->r = w[0]*d[0]->r + w[1]*d[1]->r + w[2]*d[2]->r + w[3]*d[3]->r;
+        new->g = w[0]*d[0]->g + w[1]*d[1]->g + w[2]*d[2]->g + w[3]*d[3]->g;
+        new->b = w[0]*d[0]->b + w[1]*d[1]->b + w[2]*d[2]->b + w[3]*d[3]->b;
+        new->a = w[0]*d[0]->a + w[1]*d[1]->a + w[2]*d[2]->a + w[3]*d[3]->a;
+        *dataOut = new;
+     }
+
+     If the algorithm detects an intersection, then the "combine" callback
+     must be defined, and must write a non-NULL pointer into "dataOut".
+     Otherwise the GLU_TESS_NEED_COMBINE_CALLBACK error occurs, and no
+     output is generated.  This is the only error that can occur during
+     tesselation and rendering.
+
+
+  Control over Tesselation
+  ------------------------
+  
+   void gluTessProperty( GLUtesselator *tess, GLenum which, GLUcoord value );
+
+   Properties defined:
+
+    - GLU_TESS_WINDING_RULE.  Possible values:
+
+	  GLU_TESS_WINDING_ODD
+	  GLU_TESS_WINDING_NONZERO
+	  GLU_TESS_WINDING_POSITIVE
+	  GLU_TESS_WINDING_NEGATIVE
+	  GLU_TESS_WINDING_ABS_GEQ_TWO
+
+      The input contours parition the plane into regions.  A winding
+      rule determines which of these regions are inside the polygon.
+      
+      For a single contour C, the winding number of a point x is simply
+      the signed number of revolutions we make around x as we travel
+      once around C (where CCW is positive).  When there are several
+      contours, the individual winding numbers are summed.  This
+      procedure associates a signed integer value with each point x in
+      the plane.  Note that the winding number is the same for all
+      points in a single region.
+
+      The winding rule classifies a region as "inside" if its winding
+      number belongs to the chosen category (odd, nonzero, positive,
+      negative, or absolute value of at least two).  The current GLU
+      tesselator implements the "odd" rule.  The "nonzero" rule is another
+      common way to define the interior.  The other three rules are
+      useful for polygon CSG operations (see below).
+
+    - GLU_TESS_BOUNDARY_ONLY.  Values: TRUE (non-zero) or FALSE (zero).
+
+      If TRUE, returns a set of closed contours which separate the
+      polygon interior and exterior (rather than a tesselation).
+      Exterior contours are oriented CCW with respect to the normal,
+      interior contours are oriented CW.  The GLU_TESS_BEGIN callback
+      uses the type GL_LINE_LOOP for each contour.
+      
+    - GLU_TESS_TOLERANCE.  Value: a real number between 0.0 and 1.0.
+
+      This specifies a tolerance for merging features to reduce the size
+      of the output.  For example, two vertices which are very close to
+      each other might be replaced by a single vertex.  The tolerance
+      is multiplied by the largest coordinate magnitude of any input vertex;
+      this specifies the maximum distance that any feature can move as the
+      result of a single merge operation.  If a single feature takes part
+      in several merge operations, the total distance moved could be larger.
+
+      Feature merging is completely optional; the tolerance is only a hint.
+      The implementation is free to merge in some cases and not in others,
+      or to never merge features at all.  The default tolerance is zero.
+      
+      The current implementation merges vertices only if they are exactly
+      coincident, regardless of the current tolerance.  A vertex is
+      spliced into an edge only if the implementation is unable to
+      distinguish which side of the edge the vertex lies on.
+      Two edges are merged only when both endpoints are identical.
+
+
+   void gluTessNormal( GLUtesselator *tess,
+		      GLUcoord x, GLUcoord y, GLUcoord z )
+
+    - Lets the user supply the polygon normal, if known.  All input data
+      is projected into a plane perpendicular to the normal before
+      tesselation.  All output triangles are oriented CCW with
+      respect to the normal (CW orientation can be obtained by
+      reversing the sign of the supplied normal).  For example, if
+      you know that all polygons lie in the x-y plane, call
+      "gluTessNormal(tess, 0.0, 0.0, 1.0)" before rendering any polygons.
+      
+    - If the supplied normal is (0,0,0) (the default value), the
+      normal is determined as follows.  The direction of the normal,
+      up to its sign, is found by fitting a plane to the vertices,
+      without regard to how the vertices are connected.  It is
+      expected that the input data lies approximately in plane;
+      otherwise projection perpendicular to the computed normal may
+      substantially change the geometry.  The sign of the normal is
+      chosen so that the sum of the signed areas of all input contours
+      is non-negative (where a CCW contour has positive area).
+    
+    - The supplied normal persists until it is changed by another
+      call to gluTessNormal.
+
+
+  Backward compatibility with the GLU tesselator
+  ----------------------------------------------
+
+  The preferred interface is the one described above.  The following
+  routines are obsolete, and are provided only for backward compatibility:
+
+    typedef GLUtesselator GLUtriangulatorObj;	/* obsolete name */
+
+    void gluBeginPolygon( GLUtesselator *tess );
+    void gluNextContour( GLUtesselator *tess, GLenum type );
+    void gluEndPolygon( GLUtesselator *tess );
+  
+  "type" is one of GLU_EXTERIOR, GLU_INTERIOR, GLU_CCW, GLU_CW, or
+  GLU_UNKNOWN.  It is ignored by the current GLU tesselator.
+  
+  GLU_BEGIN, GLU_VERTEX, GLU_END, GLU_ERROR, and GLU_EDGE_FLAG are defined
+  as synonyms for GLU_TESS_BEGIN, GLU_TESS_VERTEX, GLU_TESS_END,
+  GLU_TESS_ERROR, and GLU_TESS_EDGE_FLAG.
+
+
+Polygon CSG operations
+----------------------
+
+  The features of the tesselator make it easy to find the union, difference,
+  or intersection of several polygons.
+
+  First, assume that each polygon is defined so that the winding number
+  is 0 for each exterior region, and 1 for each interior region.  Under
+  this model, CCW contours define the outer boundary of the polygon, and
+  CW contours define holes.  Contours may be nested, but a nested
+  contour must be oriented oppositely from the contour that contains it.
+
+  If the original polygons do not satisfy this description, they can be
+  converted to this form by first running the tesselator with the
+  GLU_TESS_BOUNDARY_ONLY property turned on.  This returns a list of
+  contours satisfying the restriction above.  By allocating two
+  tesselator objects, the callbacks from one tesselator can be fed
+  directly to the input of another.
+
+  Given two or more polygons of the form above, CSG operations can be
+  implemented as follows:
+
+  Union
+     Draw all the input contours as a single polygon.  The winding number
+     of each resulting region is the number of original polygons
+     which cover it.  The union can be extracted using the
+     GLU_TESS_WINDING_NONZERO or GLU_TESS_WINDING_POSITIVE winding rules.
+     Note that with the nonzero rule, we would get the same result if
+     all contour orientations were reversed.
+
+  Intersection (two polygons at a time only)
+     Draw a single polygon using the contours from both input polygons.
+     Extract the result using GLU_TESS_WINDING_ABS_GEQ_TWO.  (Since this
+     winding rule looks at the absolute value, reversing all contour
+     orientations does not change the result.)
+
+  Difference
+  
+     Suppose we want to compute A \ (B union C union D).  Draw a single
+     polygon consisting of the unmodified contours from A, followed by
+     the contours of B,C,D with the vertex order reversed (this changes
+     the winding number of the interior regions to -1).  To extract the
+     result, use the GLU_TESS_WINDING_POSITIVE rule.
+   
+     If B,C,D are the result of a GLU_TESS_BOUNDARY_ONLY call, an
+     alternative to reversing the vertex order is to reverse the sign of
+     the supplied normal.  For example in the x-y plane, call
+     gluTessNormal( tess, 0.0, 0.0, -1.0 ).
+ 
+
+Performance
+-----------
+
+  The tesselator is not intended for immediate-mode rendering; when
+  possible the output should be cached in a user structure or display
+  list.  General polygon tesselation is an inherently difficult problem,
+  especially given the goal of extreme robustness.
+
+  The implementation makes an effort to output a small number of fans
+  and strips; this should improve the rendering performance when the
+  output is used in a display list.
+
+  Single-contour input polygons are first tested to see whether they can
+  be rendered as a triangle fan with respect to the first vertex (to
+  avoid running the full decomposition algorithm on convex polygons).
+  Non-convex polygons may be rendered by this "fast path" as well, if
+  the algorithm gets lucky in its choice of a starting vertex.
+
+  For best performance follow these guidelines:
+
+   - supply the polygon normal, if available, using gluTessNormal().
+     This represents about 10% of the computation time.  For example,
+     if all polygons lie in the x-y plane, use gluTessNormal(tess,0,0,1).
+
+   - render many polygons using the same tesselator object, rather than
+     allocating a new tesselator for each one.  (In a multi-threaded,
+     multi-processor environment you may get better performance using
+     several tesselators.)
+
+
+Comparison with the GLU tesselator
+----------------------------------
+
+  On polygons which make it through the "fast path", the tesselator is
+  3 to 5 times faster than the GLU tesselator.
+
+  On polygons which don't make it through the fast path (but which don't
+  have self-intersections or degeneracies), it is about 2 times slower.
+
+  On polygons with self-intersections or degeneraces, there is nothing
+  to compare against.
+
+  The new tesselator generates many more fans and strips, reducing the
+  number of vertices that need to be sent to the hardware.
+
+  Key to the statistics:
+
+	vert		number of input vertices on all contours
+	cntr		number of input contours
+	tri		number of triangles in all output primitives
+	strip		number of triangle strips
+	fan		number of triangle fans
+	ind		number of independent triangles
+	ms		number of milliseconds for tesselation

+
+This is only a very brief overview.  There is quite a bit of
+additional documentation in the source code itself.
+
+
+Goals of robust tesselation
+---------------------------
+
+The tesselation algorithm is fundamentally a 2D algorithm.  We
+initially project all data into a plane; our goal is to robustly
+tesselate the projected data.  The same topological tesselation is
+then applied to the input data.
+
+Topologically, the output should always be a tesselation.  If the
+input is even slightly non-planar, then some triangles will
+necessarily be back-facing when viewed from some angles, but the goal
+is to minimize this effect.
+
+The algorithm needs some capability of cleaning up the input data as
+well as the numerical errors in its own calculations.  One way to do
+this is to specify a tolerance as defined above, and clean up the
+input and output during the line sweep process.  At the very least,
+the algorithm must handle coincident vertices, vertices incident to an
+edge, and coincident edges.
+
+
+Phases of the algorithm
+-----------------------
+
+1. Find the polygon normal N.
+2. Project the vertex data onto a plane.  It does not need to be
+   perpendicular to the normal, eg. we can project onto the plane
+   perpendicular to the coordinate axis whose dot product with N
+   is largest.
+3. Using a line-sweep algorithm, partition the plane into x-monotone
+   regions.  Any vertical line intersects an x-monotone region in
+   at most one interval.
+4. Triangulate the x-monotone regions.
+5. Group the triangles into strips and fans.
+
+
+Finding the normal vector
+-------------------------
+
+A common way to find a polygon normal is to compute the signed area
+when the polygon is projected along the three coordinate axes.  We
+can't do this, since contours can have zero area without being
+degenerate (eg. a bowtie).
+
+We fit a plane to the vertex data, ignoring how they are connected
+into contours.  Ideally this would be a least-squares fit; however for
+our purpose the accuracy of the normal is not important.  Instead we
+find three vertices which are widely separated, and compute the normal
+to the triangle they form.  The vertices are chosen so that the
+triangle has an area at least 1/sqrt(3) times the largest area of any
+triangle formed using the input vertices.  
+
+The contours do affect the orientation of the normal; after computing
+the normal, we check that the sum of the signed contour areas is
+non-negative, and reverse the normal if necessary.
+
+
+Projecting the vertices
+-----------------------
+
+We project the vertices onto a plane perpendicular to one of the three
+coordinate axes.  This helps numerical accuracy by removing a
+transformation step between the original input data and the data
+processed by the algorithm.  The projection also compresses the input
+data; the 2D distance between vertices after projection may be smaller
+than the original 2D distance.  However by choosing the coordinate
+axis whose dot product with the normal is greatest, the compression
+factor is at most 1/sqrt(3).
+
+Even though the *accuracy* of the normal is not that important (since
+we are projecting perpendicular to a coordinate axis anyway), the
+*robustness* of the computation is important.  For example, if there
+are many vertices which lie almost along a line, and one vertex V
+which is well-separated from the line, then our normal computation
+should involve V otherwise the results will be garbage.
+
+The advantage of projecting perpendicular to the polygon normal is
+that computed intersection points will be as close as possible to
+their ideal locations.  To get this behavior, define TRUE_PROJECT.
+
+
+The Line Sweep
+--------------
+
+There are three data structures: the mesh, the event queue, and the
+edge dictionary.
+
+The mesh is a "quad-edge" data structure which records the topology of
+the current decomposition; for details see the include file "mesh.h".
+
+The event queue simply holds all vertices (both original and computed
+ones), organized so that we can quickly extract the vertex with the
+minimum x-coord (and among those, the one with the minimum y-coord).
+
+The edge dictionary describes the current intersection of the sweep
+line with the regions of the polygon.  This is just an ordering of the
+edges which intersect the sweep line, sorted by their current order of
+intersection.  For each pair of edges, we store some information about
+the monotone region between them -- these are call "active regions"
+(since they are crossed by the current sweep line).
+
+The basic algorithm is to sweep from left to right, processing each
+vertex.  The processed portion of the mesh (left of the sweep line) is
+a planar decomposition.  As we cross each vertex, we update the mesh
+and the edge dictionary, then we check any newly adjacent pairs of
+edges to see if they intersect.
+
+A vertex can have any number of edges.  Vertices with many edges can
+be created as vertices are merged and intersection points are
+computed.  For unprocessed vertices (right of the sweep line), these
+edges are in no particular order around the vertex; for processed
+vertices, the topological ordering should match the geometric ordering.
+
+The vertex processing happens in two phases: first we process are the
+left-going edges (all these edges are currently in the edge
+dictionary).  This involves:
+
+ - deleting the left-going edges from the dictionary;
+ - relinking the mesh if necessary, so that the order of these edges around
+   the event vertex matches the order in the dictionary;
+ - marking any terminated regions (regions which lie between two left-going
+   edges) as either "inside" or "outside" according to their winding number.
+
+When there are no left-going edges, and the event vertex is in an
+"interior" region, we need to add an edge (to split the region into
+monotone pieces).  To do this we simply join the event vertex to the
+rightmost left endpoint of the upper or lower edge of the containing
+region.
+
+Then we process the right-going edges.  This involves:
+
+ - inserting the edges in the edge dictionary;
+ - computing the winding number of any newly created active regions.
+   We can compute this incrementally using the winding of each edge
+   that we cross as we walk through the dictionary.
+ - relinking the mesh if necessary, so that the order of these edges around
+   the event vertex matches the order in the dictionary;
+ - checking any newly adjacent edges for intersection and/or merging.
+
+If there are no right-going edges, again we need to add one to split
+the containing region into monotone pieces.  In our case it is most
+convenient to add an edge to the leftmost right endpoint of either
+containing edge; however we may need to change this later (see the
+code for details).
+
+
+Invariants
+----------
+
+These are the most important invariants maintained during the sweep.
+We define a function VertLeq(v1,v2) which defines the order in which
+vertices cross the sweep line, and a function EdgeLeq(e1,e2; loc)
+which says whether e1 is below e2 at the sweep event location "loc".
+This function is defined only at sweep event locations which lie
+between the rightmost left endpoint of {e1,e2}, and the leftmost right
+endpoint of {e1,e2}.
+
+Invariants for the Edge Dictionary.
+
+ - Each pair of adjacent edges e2=Succ(e1) satisfies EdgeLeq(e1,e2)
+   at any valid location of the sweep event.
+ - If EdgeLeq(e2,e1) as well (at any valid sweep event), then e1 and e2
+   share a common endpoint.
+ - For each e in the dictionary, e->Dst has been processed but not e->Org.
+ - Each edge e satisfies VertLeq(e->Dst,event) && VertLeq(event,e->Org)
+   where "event" is the current sweep line event.
+ - No edge e has zero length.
+ - No two edges have identical left and right endpoints.
+ 
+Invariants for the Mesh (the processed portion).
+
+ - The portion of the mesh left of the sweep line is a planar graph,
+   ie. there is *some* way to embed it in the plane.
+ - No processed edge has zero length.
+ - No two processed vertices have identical coordinates.
+ - Each "inside" region is monotone, ie. can be broken into two chains
+   of monotonically increasing vertices according to VertLeq(v1,v2)
+   - a non-invariant: these chains may intersect (slightly) due to
+     numerical errors, but this does not affect the algorithm's operation.
+
+Invariants for the Sweep.
+
+ - If a vertex has any left-going edges, then these must be in the edge
+   dictionary at the time the vertex is processed.
+ - If an edge is marked "fixUpperEdge" (it is a temporary edge introduced
+   by ConnectRightVertex), then it is the only right-going edge from
+   its associated vertex.  (This says that these edges exist only
+   when it is necessary.)
+
+
+Robustness
+----------
+
+The key to the robustness of the algorithm is maintaining the
+invariants above, especially the correct ordering of the edge
+dictionary.  We achieve this by:
+
+  1. Writing the numerical computations for maximum precision rather
+     than maximum speed.
+     
+  2. Making no assumptions at all about the results of the edge
+     intersection calculations -- for sufficiently degenerate inputs,
+     the computed location is not much better than a random number.
+     
+  3. When numerical errors violate the invariants, restore them
+     by making *topological* changes when necessary (ie. relinking
+     the mesh structure).
+     
+     
+Triangulation and Grouping
+--------------------------
+
+We finish the line sweep before doing any triangulation.  This is
+because even after a monotone region is complete, there can be further
+changes to its vertex data because of further vertex merging.
+
+After triangulating all monotone regions, we want to group the
+triangles into fans and strips.  We do this using a greedy approach.
+The triangulation itself is not optimized to reduce the number of
+primitives; we just try to get a reasonable decomposition of the
+computed triangulation.

+/* The mesh structure is similar in spirit, notation, and operations
+ * to the "quad-edge" structure (see L. Guibas and J. Stolfi, Primitives
+ * for the manipulation of general subdivisions and the computation of
+ * Voronoi diagrams, ACM Transactions on Graphics, 4(2):74-123, April 1985).
+ * For a simplified description, see the course notes for CS348a,
+ * "Mathematical Foundations of Computer Graphics", available at the
+ * Stanford bookstore (and taught during the fall quarter).
+ * The implementation also borrows a tiny subset of the graph-based approach
+ * use in Mantyla's Geometric Work Bench (see M. Mantyla, An Introduction
+ * to Sold Modeling, Computer Science Press, Rockville, Maryland, 1988).
+ *
+ * The fundamental data structure is the "half-edge".  Two half-edges
+ * go together to make an edge, but they point in opposite directions.
+ * Each half-edge has a pointer to its mate (the "symmetric" half-edge Sym),
+ * its origin vertex (Org), the face on its left side (Lface), and the
+ * adjacent half-edges in the CCW direction around the origin vertex
+ * (Onext) and around the left face (Lnext).  There is also a "next"
+ * pointer for the global edge list (see below).
+ *
+ * The notation used for mesh navigation:
+ *	Sym   = the mate of a half-edge (same edge, but opposite direction)
+ *	Onext = edge CCW around origin vertex (keep same origin)
+ *	Dnext = edge CCW around destination vertex (keep same dest)
+ *	Lnext = edge CCW around left face (dest becomes new origin)
+ *	Rnext = edge CCW around right face (origin becomes new dest)
+ *
+ * "prev" means to substitute CW for CCW in the definitions above.
+ *
+ * The mesh keeps global lists of all vertices, faces, and edges,
+ * stored as doubly-linked circular lists with a dummy header node.
+ * The mesh stores pointers to these dummy headers (vHead, fHead, eHead).
+ *
+ * The circular edge list is special; since half-edges always occur
+ * in pairs (e and e->Sym), each half-edge stores a pointer in only
+ * one direction.  Starting at eHead and following the e->next pointers
+ * will visit each *edge* once (ie. e or e->Sym, but not both).
+ * e->Sym stores a pointer in the opposite direction, thus it is
+ * always true that e->Sym->next->Sym->next == e.
+ *
+ * Each vertex has a pointer to next and previous vertices in the
+ * circular list, and a pointer to a half-edge with this vertex as
+ * the origin (NULL if this is the dummy header).  There is also a
+ * field "data" for client data.
+ *
+ * Each face has a pointer to the next and previous faces in the
+ * circular list, and a pointer to a half-edge with this face as
+ * the left face (NULL if this is the dummy header).  There is also
+ * a field "data" for client data.
+ *
+ * Note that what we call a "face" is really a loop; faces may consist
+ * of more than one loop (ie. not simply connected), but there is no
+ * record of this in the data structure.  The mesh may consist of
+ * several disconnected regions, so it may not be possible to visit
+ * the entire mesh by starting at a half-edge and traversing the edge
+ * structure.
+ *
+ * The mesh does NOT support isolated vertices; a vertex is deleted along
+ * with its last edge.  Similarly when two faces are merged, one of the
+ * faces is deleted (see __gl_meshDelete below).  For mesh operations,
+ * all face (loop) and vertex pointers must not be NULL.  However, once
+ * mesh manipulation is finished, __gl_MeshZapFace can be used to delete
+ * faces of the mesh, one at a time.  All external faces can be "zapped"
+ * before the mesh is returned to the client; then a NULL face indicates
+ * a region which is not part of the output polygon.

+/* The mesh operations below have three motivations: completeness,
+ * convenience, and efficiency.  The basic mesh operations are MakeEdge,
+ * Splice, and Delete.  All the other edge operations can be implemented
+ * in terms of these.  The other operations are provided for convenience
+ * and/or efficiency.
+ *
+ * When a face is split or a vertex is added, they are inserted into the
+ * global list *before* the existing vertex or face (ie. e->Org or e->Lface).
+ * This makes it easier to process all vertices or faces in the global lists
+ * without worrying about processing the same data twice.  As a convenience,
+ * when a face is split, the "inside" flag is copied from the old face.
+ * Other internal data (v->data, v->activeRegion, f->data, f->marked,
+ * f->trail, e->winding) is set to zero.
+ *
+ * ********************** Basic Edge Operations **************************
+ *
+ * __gl_meshMakeEdge( mesh ) creates one edge, two vertices, and a loop.
+ * The loop (face) consists of the two new half-edges.
+ *
+ * __gl_meshSplice( eOrg, eDst ) is the basic operation for changing the
+ * mesh connectivity and topology.  It changes the mesh so that
+ *	eOrg->Onext <- OLD( eDst->Onext )
+ *	eDst->Onext <- OLD( eOrg->Onext )
+ * where OLD(...) means the value before the meshSplice operation.
+ *
+ * This can have two effects on the vertex structure:
+ *  - if eOrg->Org != eDst->Org, the two vertices are merged together
+ *  - if eOrg->Org == eDst->Org, the origin is split into two vertices
+ * In both cases, eDst->Org is changed and eOrg->Org is untouched.
+ *
+ * Similarly (and independently) for the face structure,
+ *  - if eOrg->Lface == eDst->Lface, one loop is split into two
+ *  - if eOrg->Lface != eDst->Lface, two distinct loops are joined into one
+ * In both cases, eDst->Lface is changed and eOrg->Lface is unaffected.
+ *
+ * __gl_meshDelete( eDel ) removes the edge eDel.  There are several cases:
+ * if (eDel->Lface != eDel->Rface), we join two loops into one; the loop
+ * eDel->Lface is deleted.  Otherwise, we are splitting one loop into two;
+ * the newly created loop will contain eDel->Dst.  If the deletion of eDel
+ * would create isolated vertices, those are deleted as well.
+ *
+ * ********************** Other Edge Operations **************************
+ *
+ * __gl_meshAddEdgeVertex( eOrg ) creates a new edge eNew such that
+ * eNew == eOrg->Lnext, and eNew->Dst is a newly created vertex.
+ * eOrg and eNew will have the same left face.
+ *
+ * __gl_meshSplitEdge( eOrg ) splits eOrg into two edges eOrg and eNew,
+ * such that eNew == eOrg->Lnext.  The new vertex is eOrg->Dst == eNew->Org.
+ * eOrg and eNew will have the same left face.
+ *
+ * __gl_meshConnect( eOrg, eDst ) creates a new edge from eOrg->Dst
+ * to eDst->Org, and returns the corresponding half-edge eNew.
+ * If eOrg->Lface == eDst->Lface, this splits one loop into two,
+ * and the newly created loop is eNew->Lface.  Otherwise, two disjoint
+ * loops are merged into one, and the loop eDst->Lface is destroyed.
+ *
+ * ************************ Other Operations *****************************
+ *
+ * __gl_meshNewMesh() creates a new mesh with no edges, no vertices,
+ * and no loops (what we usually call a "face").
+ *
+ * __gl_meshUnion( mesh1, mesh2 ) forms the union of all structures in
+ * both meshes, and returns the new mesh (the old meshes are destroyed).
+ *
+ * __gl_meshDeleteMesh( mesh ) will free all storage for any valid mesh.
+ *
+ * __gl_meshZapFace( fZap ) destroys a face and removes it from the
+ * global face list.  All edges of fZap will have a NULL pointer as their
+ * left face.  Any edges which also have a NULL pointer as their right face
+ * are deleted entirely (along with any isolated vertices this produces).
+ * An entire mesh can be deleted by zapping its faces, one at a time,
+ * in any order.  Zapped faces cannot be used in further mesh operations!
+ *
+ * __gl_meshCheckMesh( mesh ) checks a mesh for self-consistency.

+ * region in a single interval.  
+ *
+ * Tessellation consists of adding interior edges (actually pairs of
+ * half-edges), to split the region into non-overlapping triangles.
+ *
+ * The basic idea is explained in Preparata and Shamos (which I don''t
+ * have handy right now), although their implementation is more
+ * complicated than this one.  The are two edge chains, an upper chain
+ * and a lower chain.  We process all vertices from both chains in order,
+ * from right to left.
+ *
+ * The algorithm ensures that the following invariant holds after each
+ * vertex is processed: the untessellated region consists of two
+ * chains, where one chain (say the upper) is a single edge, and
+ * the other chain is concave.  The left vertex of the single edge
+ * is always to the left of all vertices in the concave chain.
+ *
+ * Each step consists of adding the rightmost unprocessed vertex to one
+ * of the two chains, and forming a fan of triangles from the rightmost
+ * of two chain endpoints.  Determining whether we can add each triangle
+ * to the fan is a simple orientation test.  By making the fan as large

+#
+#  updated : by Heromyth, on 2007-7-21
+#  Email   : zxpmyth@yahoo.com.cn
+#  Bugs    : 1) All the default settings work fine. But the setting X86=1 can't work. 
+#            The others havn't been tested yet.
+#            2) The generated DLLs are *not* compatible with the ones built
+#            with the other compilers like VC8, especially for GLUT. 
+#            3) Although more tests are needed, it can be used individually!
+
+
+#
+#  Available options:
+#
+#    Environment variables:
+#	CFLAGS
+#
+#	GLIDE		path to Glide3 SDK; used with FX.
+#			default = $(TOP)/glide3
+#	FX=1		build for 3dfx Glide3. Note that this disables
+#			compilation of most WMesa code and requires fxMesa.
+#			As a consequence, you'll need the Win32 Glide3
+#			library to build any application.
+#			default = no
+#	ICD=1		build the installable client driver interface
+#			(windows opengl driver interface)
+#			default = no
+#	X86=1		optimize for x86 (if possible, use MMX, SSE, 3DNow).
+#			default = no
+#
+#    Targets:
+#	all:		build GL
+#	clean:		remove object files

+/*	mmx.h
+
+	MultiMedia eXtensions GCC interface library for IA32.
+
+	To use this library, simply include this header file
+	and compile with GCC.  You MUST have inlining enabled
+	in order for mmx_ok() to work; this can be done by
+	simply using -O on the GCC command line.
+
+	Compiling with -DMMX_TRACE will cause detailed trace
+	output to be sent to stderr for each mmx operation.
+	This adds lots of code, and obviously slows execution to
+	a crawl, but can be very useful for debugging.
+
+	THIS SOFTWARE IS PROVIDED ``AS IS'' AND WITHOUT ANY
+	EXPRESS OR IMPLIED WARRANTIES, INCLUDING, WITHOUT
+	LIMITATION, THE IMPLIED WARRANTIES OF MERCHANTABILITY
+	AND FITNESS FOR ANY PARTICULAR PURPOSE.
+
+	1997-98 by H. Dietz and R. Fisher
+
+ History:
+	97-98*	R.Fisher	Early versions
+	980501	R.Fisher	Original Release
+	980611*	H.Dietz		Rewrite, correctly implementing inlines, and
+		R.Fisher	 including direct register accesses.
+	980616	R.Fisher	Release of 980611 as 980616.
+	980714	R.Fisher	Minor corrections to Makefile, etc.
+	980715	R.Fisher	mmx_ok() now prevents optimizer from using
+				 clobbered values.
+				mmx_ok() now checks if cpuid instruction is
+				 available before trying to use it.
+	980726*	R.Fisher	mm_support() searches for AMD 3DNow, Cyrix
+				 Extended MMX, and standard MMX.  It returns a
+				 value which is positive if any of these are
+				 supported, and can be masked with constants to
+				 see which.  mmx_ok() is now a call to this
+	980726*	R.Fisher	Added i2r support for shift functions
+	980919	R.Fisher	Fixed AMD extended feature recognition bug.
+	980921	R.Fisher	Added definition/check for _MMX_H.
+				Added "float s[2]" to mmx_t for use with
+				  3DNow and EMMX.  So same mmx_t can be used.
+	981013	R.Fisher	Fixed cpuid function 1 bug (looked at wrong reg)
+				Fixed psllq_i2r error in mmxtest.c
+
+	* Unreleased (internal or interim) versions
+
+ Notes:
+	It appears that the latest gas has the pand problem fixed, therefore
+	  I'll undefine BROKEN_PAND by default.
+	String compares may be quicker than the multiple test/jumps in vendor
+	  test sequence in mmx_ok(), but I'm not concerned with that right now.
+
+ Acknowledgments:
+	Jussi Laako for pointing out the errors ultimately found to be
+	  connected to the failure to notify the optimizer of clobbered values.
+	Roger Hardiman for reminding us that CPUID isn't everywhere, and that
+	  someone may actually try to use this on a machine without CPUID.
+	  Also for suggesting code for checking this.
+	Robert Dale for pointing out the AMD recognition bug.
+	Jimmy Mayfield and Carl Witty for pointing out the Intel recognition
+	  bug.
+	Carl Witty for pointing out the psllq_i2r test bug.

+ * Creates a set of \c __GLcontextModes that a driver will expose.
+ * 
+ * A set of \c __GLcontextModes will be created based on the supplied
+ * parameters.  The number of modes processed will be 2 *
+ * \c num_depth_stencil_bits * \c num_db_modes.
+ * 
+ * For the most part, data is just copied from \c depth_bits, \c stencil_bits,
+ * \c db_modes, and \c visType into each \c __GLcontextModes element.
+ * However, the meanings of \c fb_format and \c fb_type require further
+ * explanation.  The \c fb_format specifies which color components are in
+ * each pixel and what the default order is.  For example, \c GL_RGB specifies
+ * that red, green, blue are available and red is in the "most significant"
+ * position and blue is in the "least significant".  The \c fb_type specifies
+ * the bit sizes of each component and the actual ordering.  For example, if
+ * \c GL_UNSIGNED_SHORT_5_6_5_REV is specified with \c GL_RGB, bits [15:11]
+ * are the blue value, bits [10:5] are the green value, and bits [4:0] are
+ * the red value.
+ * 
+ * One sublte issue is the combination of \c GL_RGB  or \c GL_BGR and either
+ * of the \c GL_UNSIGNED_INT_8_8_8_8 modes.  The resulting mask values in the
+ * \c __GLcontextModes structure is \b identical to the \c GL_RGBA or
+ * \c GL_BGRA case, except the \c alphaMask is zero.  This means that, as
+ * far as this routine is concerned, \c GL_RGB with \c GL_UNSIGNED_INT_8_8_8_8
+ * still uses 32-bits.
+ *
+ * If in doubt, look at the tables used in the function.
+ * 
+ * \param ptr_to_modes  Pointer to a pointer to a linked list of
+ *                      \c __GLcontextModes.  Upon completion, a pointer to
+ *                      the next element to be process will be stored here.
+ *                      If the function fails and returns \c GL_FALSE, this
+ *                      value will be unmodified, but some elements in the
+ *                      linked list may be modified.
+ * \param fb_format     Format of the framebuffer.  Currently only \c GL_RGB,
+ *                      \c GL_RGBA, \c GL_BGR, and \c GL_BGRA are supported.
+ * \param fb_type       Type of the pixels in the framebuffer.  Currently only
+ *                      \c GL_UNSIGNED_SHORT_5_6_5, 
+ *                      \c GL_UNSIGNED_SHORT_5_6_5_REV,
+ *                      \c GL_UNSIGNED_INT_8_8_8_8, and
+ *                      \c GL_UNSIGNED_INT_8_8_8_8_REV are supported.
+ * \param depth_bits    Array of depth buffer sizes to be exposed.
+ * \param stencil_bits  Array of stencil buffer sizes to be exposed.
+ * \param num_depth_stencil_bits  Number of entries in both \c depth_bits and
+ *                      \c stencil_bits.
+ * \param db_modes      Array of buffer swap modes.  If an element has a
+ *                      value of \c GLX_NONE, then it represents a
+ *                      single-buffered mode.  Other valid values are
+ *                      \c GLX_SWAP_EXCHANGE_OML, \c GLX_SWAP_COPY_OML, and
+ *                      \c GLX_SWAP_UNDEFINED_OML.  See the
+ *                      GLX_OML_swap_method extension spec for more details.
+ * \param num_db_modes  Number of entries in \c db_modes.
+ * \param msaa_samples  Array of msaa sample count. 0 represents a visual
+ *                      without a multisample buffer.
+ * \param num_msaa_modes Number of entries in \c msaa_samples.
+ * \param visType       GLX visual type.  Usually either \c GLX_TRUE_COLOR or
+ *                      \c GLX_DIRECT_COLOR.
+ * 
+ * \returns
+ * \c GL_TRUE on success or \c GL_FALSE on failure.  Currently the only
+ * cause of failure is a bad parameter (i.e., unsupported \c fb_format or
+ * \c fb_type).
+ * 
+ * \todo
+ * There is currently no way to support packed RGB modes (i.e., modes with
+ * exactly 3 bytes per pixel) or floating-point modes.  This could probably
+ * be done by creating some new, private enums with clever names likes
+ * \c GL_UNSIGNED_3BYTE_8_8_8, \c GL_4FLOAT_32_32_32_32, 
+ * \c GL_4HALF_16_16_16_16, etc.  We can cross that bridge when we come to it.

+# Convenient makefile for managing translations.
+
+# Prerequisites:
+# - GNU gettext
+# - Python
+
+# Adding new translations
+# -----------------------
+
+# To start working on a new translation edit the POS=... line
+# below. If you want to add for example a french translation, add
+# fr.po.
+
+# Then run "make po" to generate a fresh .po file from translatable
+# strings in t_options.h. Now you can edit the new .po file (fr.po in
+# the example above) to translate the strings. Please make sure that
+# your editor encodes the file in UTF-8.
+
+# Updating existing translations
+# ------------------------------
+
+# Run "make po" to update .po files with new translatable strings from
+# t_options.h. Now you can edit the .po files you're interested
+# in. Please make sure that your editor encodes the file in UTF-8.
+
+# Updating options.h
+# ------------------
+
+# Finally run "make" to generate options.h from t_options.h with all
+# translations. Now you can rebuild the drivers. Any common options
+# used by the drivers will have option descriptions with the latest
+# translations.
+
+# Publishing translations
+# -----------------------
+
+# To get your translation(s) into Mesa CVS, please send me your
+# <lang>.po file.

+# More information:
+# - info gettext

+;DESCRIPTION 'Mesa (OpenGL work-alike) for Win32'
+VERSION 6.5
+;
+; Module definition file for Mesa (OPENGL32.DLL)
+;
+; Note: The OpenGL functions use the STDCALL
+; function calling convention.  Microsoft's
+; OPENGL32 uses this convention and so must the
+; Mesa OPENGL32 so that the Mesa DLL can be used
+; as a drop-in replacement.
+;
+; The linker exports STDCALL entry points with
+; 'decorated' names; e.g., _glBegin@0, where the
+; trailing number is the number of bytes of 
+; parameter data pushed onto the stack.  The
+; callee is responsible for popping this data
+; off the stack, usually via a RETF n instruction.
+;
+; However, the Microsoft OPENGL32.DLL does not export
+; the decorated names, even though the calling convention
+; is STDCALL.  So, this module definition file is
+; needed to force the Mesa OPENGL32.DLL to export the
+; symbols in the same manner as the Microsoft DLL.
+; Were it not for this problem, this file would not
+; be needed (for the gl* functions) since the entry
+; points are compiled with dllexport declspec.
+;
+; However, this file is still needed to export "internal"
+; Mesa symbols for the benefit of the OSMESA32.DLL.

+ * This file manages the OpenGL API dispatch layer.
+ * The dispatch table (struct _glapi_table) is basically just a list
+ * of function pointers.
+ * There are functions to set/get the current dispatch table for the
+ * current thread and to manage registration/dispatch of dynamically
+ * added extension functions.
+ *
+ * It's intended that this file and the other glapi*.[ch] files are
+ * flexible enough to be reused in several places:  XFree86, DRI-
+ * based libGL.so, and perhaps the SGI SI.
+ *
+ * NOTE: There are no dependencies on Mesa in this code.
+ *
+ * Versions (API changes):
+ *   2000/02/23  - original version for Mesa 3.3 and XFree86 4.0
+ *   2001/01/16  - added dispatch override feature for Mesa 3.5
+ *   2002/06/28  - added _glapi_set_warning_func(), Mesa 4.1.
+ *   2002/10/01  - _glapi_get_proc_address() will now generate new entrypoints
+ *                 itself (using offset ~0).  _glapi_add_entrypoint() can be
+ *                 called afterward and it'll fill in the correct dispatch
+ *                 offset.  This allows DRI libGL to avoid probing for DRI
+ *                 drivers!  No changes to the public glapi interface.

+ * \name Current dispatch and current context control variables
+ *
+ * Depending on whether or not multithreading is support, and the type of
+ * support available, several variables are used to store the current context
+ * pointer and the current dispatch table pointer.  In the non-threaded case,
+ * the variables \c _glapi_Dispatch and \c _glapi_Context are used for this
+ * purpose.
+ *
+ * In the "normal" threaded case, the variables \c _glapi_Dispatch and
+ * \c _glapi_Context will be \c NULL if an application is detected as being
+ * multithreaded.  Single-threaded applications will use \c _glapi_Dispatch
+ * and \c _glapi_Context just like the case without any threading support.
+ * When \c _glapi_Dispatch and \c _glapi_Context are \c NULL, the thread state
+ * data \c _gl_DispatchTSD and \c ContextTSD are used.  Drivers and the
+ * static dispatch functions access these variables via \c _glapi_get_dispatch
+ * and \c _glapi_get_context.
+ *
+ * There is a race condition in setting \c _glapi_Dispatch to \c NULL.  It is
+ * possible for the original thread to be setting it at the same instant a new
+ * thread, perhaps running on a different processor, is clearing it.  Because
+ * of that, \c ThreadSafe, which can only ever be changed to \c GL_TRUE, is
+ * used to determine whether or not the application is multithreaded.
+ * 
+ * In the TLS case, the variables \c _glapi_Dispatch and \c _glapi_Context are
+ * hardcoded to \c NULL.  Instead the TLS variables \c _glapi_tls_Dispatch and
+ * \c _glapi_tls_Context are used.  Having \c _glapi_Dispatch and
+ * \c _glapi_Context be hardcoded to \c NULL maintains binary compatability
+ * between TLS enabled loaders and non-TLS DRI drivers.

+ * The Mesa GL API module is responsible for dispatching all the
+ * gl*() functions.  All GL functions are dispatched by jumping through
+ * the current dispatch table (basically a struct full of function
+ * pointers.)
+ *
+ * A per-thread current dispatch table and per-thread current context
+ * pointer are managed by this module too.
+ *
+ * This module is intended to be non-Mesa-specific so it can be used
+ * with the X/DRI libGL also.

+ * This file is a template which generates the OpenGL API entry point

+ *   KEYWORD1 - usually nothing, but might be __declspec(dllexport) on Win32
+ *   KEYWORD2 - usually nothing, but might be __stdcall on Win32
+ *   NAME(n)  - builds the final function name (usually add "gl" prefix)
+ *   DISPATCH(func, args, msg) - code to do dispatch of named function.
+ *                               msg is a printf-style debug message.
+ *   RETURN_DISPATCH(func, args, msg) - code to do dispatch with a return value
+ *
+ * Here is an example which generates the usual OpenGL functions:

+ *   #define KEYWORD2
+ *   #define NAME(func)  gl##func

+ * Mesa context and visual-related functions.
+ *
+ * There are three large Mesa data types/classes which are meant to be
+ * used by device drivers:
+ * - GLcontext: this contains the Mesa rendering state
+ * - GLvisual:  this describes the color buffer (RGB vs. ci), whether or not
+ *   there's a depth buffer, stencil buffer, etc.
+ * - GLframebuffer:  contains pointers to the depth buffer, stencil buffer,
+ *   accum buffer and alpha buffers.
+ *
+ * These types should be encapsulated by corresponding device driver
+ * data types.  See xmesa.h and xmesaP.h for an example.
+ *
+ * In OOP terms, GLcontext, GLvisual, and GLframebuffer are base classes
+ * which the device driver must derive from.
+ *
+ * The following functions create and destroy these data types.

+
+         This isn't a bad approximation of 1/sqrt.  The maximum difference from
+         1/sqrt will be around .06.  After three Newton-Raphson iterations, the
+         maximum difference is less than 4.5e-8.  (Which is actually close
+         enough to make the following bias academic...)
+
+         To get a better approximation you can add a bias to the magic
+         number.  For example, if you subtract 1/2 of the maximum difference in
+         the first approximation (.03), you will get the following function:

+         (The 3.76 to 4 range is where the result is < .5.)
+
+         This is the closest possible initial approximation, but with a maximum
+         error of 8e-11 after three NR iterations, it is still not perfect.  If
+         you subtract 0.0332281 instead of .03, the maximum error will be
+         2.5e-11 after three NR iterations, which should be about as close as
+         is possible.

+/**
+ * \file syncobj.c
+ * Sync object management.
+ *
+ * Unlike textures and other objects that are shared between contexts, sync
+ * objects are not bound to the context.  As a result, the reference counting
+ * and delete behavior of sync objects is slightly different.  References to
+ * sync objects are added:
+ *
+ *    - By \c glFencSynce.  This sets the initial reference count to 1.
+ *    - At the start of \c glClientWaitSync.  The reference is held for the
+ *      duration of the wait call.
+ *
+ * References are removed:
+ *
+ *    - By \c glDeleteSync.
+ *    - At the end of \c glClientWaitSync.
+ *
+ * Additionally, drivers may call \c _mesa_ref_sync_object and
+ * \c _mesa_unref_sync_object as needed to implement \c ServerWaitSync.
+ *
+ * As with shader objects, sync object names become invalid as soon as
+ * \c glDeleteSync is called.  For this reason \c glDeleteSync sets the
+ * \c DeletePending flag.  All functions validate object handles by testing
+ * this flag.
+ *
+ * \note
+ * Only \c GL_ARB_sync objects are shared between contexts.  If support is ever
+ * added for either \c GL_NV_fence or \c GL_APPLE_fence different semantics
+ * will need to be implemented.

+ * Horner scheme for Bezier curves

+ * Since stability is not important for displaying curve

+       *  This is composed of 5 matrices, Rz, Ry, T, Ry', Rz', multiplied
+       *  like so:  Rz * Ry * T * Ry' * Rz'.  T is the final rotation
+       *  (which is about the X-axis), and the two composite transforms
+       *  Ry' * Rz' and Rz * Ry are (respectively) the rotations necessary
+       *  from the arbitrary axis to the X-axis then back.  They are
+       *  all elementary rotations.
+       *
+       *  Rz' is a rotation about the Z-axis, to bring the axis vector
+       *  into the x-z plane.  Then Ry' is applied, rotating about the
+       *  Y-axis to bring the axis vector parallel with the X-axis.  The
+       *  rotation about the X-axis is then performed.  Ry and Rz are
+       *  simply the respective inverse transforms to bring the arbitrary
+       *  axis back to it's original orientation.  The first transforms
+       *  Rz' and Ry' are considered inverses, since the data from the
+       *  arbitrary axis gives you info on how to get to it, not how
+       *  to get away from it, and an inverse must be applied.
+       *
+       *  The basic calculation used is to recognize that the arbitrary
+       *  axis vector (x, y, z), since it is of unit length, actually
+       *  represents the sines and cosines of the angles to rotate the
+       *  X-axis to the same orientation, with theta being the angle about
+       *  Z and phi the angle about Y (in the order described above)
+       *  as follows:
+       *
+       *  cos ( theta ) = x / sqrt ( 1 - z^2 )
+       *  sin ( theta ) = y / sqrt ( 1 - z^2 )
+       *
+       *  cos ( phi ) = sqrt ( 1 - z^2 )
+       *  sin ( phi ) = z
+       *
+       *  Note that cos ( phi ) can further be inserted to the above
+       *  formulas:
+       *
+       *  cos ( theta ) = x / cos ( phi )
+       *  sin ( theta ) = y / sin ( phi )
+       *
+       *  ...etc.  Because of those relations and the standard trigonometric
+       *  relations, it is pssible to reduce the transforms down to what
+       *  is used below.  It may be that any primary axis chosen will give the
+       *  same results (modulo a sign convention) using thie method.
+       *
+       *  Particularly nice is to notice that all divisions that might
+       *  have caused trouble when parallel to certain planes or
+       *  axis go away with care paid to reducing the expressions.
+       *  After checking, it does perform correctly under all cases, since
+       *  in all the cases of division where the denominator would have
+       *  been zero, the numerator would have been zero as well, giving
+       *  the expected result.

+ * coordinates are very useful to us because they let us cull
+ * backfaces and eliminate vertices from lighting, fogging, etc
+ * calculations.  Despite the fact that this divide could be done one
+ * day in hardware, we would still have a reason to want to do it here
+ * as long as those other calculations remain in software.
+ *
+ * Clipping is a convenient place to do the divide on x86 as it should be
+ * possible to overlap with integer outcode calculations.
+ *
+ * There are two cases where we wouldn't want to do the divide in cliptest:
+ *    - When we aren't clipping.  We still might want to cull backfaces
+ *      so the divide should be done elsewhere.  This currently never
+ *      happens.
+ *
+ *    - When culling isn't likely to help us, such as when the GL culling
+ *      is disabled and we not lighting or are only lighting
+ *      one-sided.  In this situation, backface determination provides
+ *      us with no useful information.  A tricky case to detect is when
+ *      all input data is already culled, although hopefully the
+ *      application wouldn't turn on culling in such cases.
+ *
+ * We supply a buffer to hold the [x/w,y/w,z/w,1/w] values which
+ * are the result of the projection.  This is only used in the
+ * 4-vector case - in other cases, we just use the clip coordinates
+ * as the projected coordinates - they are identical.
+ *
+ * This is doubly convenient because it means the Win[] array is now
+ * of the same stride as all the others, so I can now turn map_vertices
+ * into a straight-forward matrix transformation, with asm acceleration

+Notes on program parameters, etc.
+
+The instructions we emit will use six kinds of source registers:
+
+  PROGRAM_INPUT      - input registers
+  PROGRAM_TEMPORARY  - temp registers
+  PROGRAM_ADDRESS    - address/indirect register
+  PROGRAM_SAMPLER    - texture sampler
+  PROGRAM_CONSTANT   - indexes into program->Parameters, a known constant/literal
+  PROGRAM_STATE_VAR  - indexes into program->Parameters, and may actually be:
+                       + a state variable, like "state.fog.color", or
+                       + a pointer to a "program.local[k]" parameter, or
+                       + a pointer to a "program.env[k]" parameter
+
+Basically, all the program.local[] and program.env[] values will get mapped
+into the unified gl_program->Parameters array.  This solves the problem of
+having three separate program parameter arrays.

+    INTRODUCTION
+    ------------
+
+    The task is to check the syntax of an input string. Input string is a stream of ASCII
+    characters terminated with a null-character ('\0'). Checking it using C language is
+    difficult and hard to implement without bugs. It is hard to maintain and make changes when
+    the syntax changes.
+
+    This is because of a high redundancy of the C code. Large blocks of code are duplicated with
+    only small changes. Even use of macros does not solve the problem because macros cannot
+    erase the complexity of the problem.
+
+    The resolution is to create a new language that will be highly oriented to our task. Once
+    we describe a particular syntax, we are done. We can then focus on the code that implements
+    the language. The size and complexity of it is relatively small than the code that directly
+    checks the syntax.
+
+    First, we must implement our new language. Here, the language is implemented in C, but it
+    could also be implemented in any other language. The code is listed below. We must take
+    a good care that it is bug free. This is simple because the code is simple and clean.
+
+    Next, we must describe the syntax of our new language in itself. Once created and checked
+    manually that it is correct, we can use it to check another scripts.
+
+    Note that our new language loading code does not have to check the syntax. It is because we
+    assume that the script describing itself is correct, and other scripts can be syntactically
+    checked by the former script. The loading code must only do semantic checking which leads us to
+    simple resolving references.
+
+    THE LANGUAGE
+    ------------
+
+    Here I will describe the syntax of the new language (further called "Synek"). It is mainly a
+    sequence of declarations terminated by a semicolon. The declaration consists of a symbol,
+    which is an identifier, and its definition. A definition is in turn a sequence of specifiers
+    connected with ".and" or ".or" operator. These operators cannot be mixed together in a one
+    definition. Specifier can be a symbol, string, character, character range or a special
+    keyword ".true" or ".false".
+
+    On the very beginning of the script there is a declaration of a root symbol and is in the form:
+        .syntax <root_symbol>;
+    The <root_symbol> must be on of the symbols in declaration sequence. The syntax is correct if
+    the root symbol evaluates to true. A symbol evaluates to true if the definition associated with
+    the symbol evaluates to true. Definition evaluation depends on the operator used to connect
+    specifiers in the definition. If ".and" operator is used, definition evaluates to true if and
+    only if all the specifiers evaluate to true. If ".or" operator is used, definition evalutes to
+    true if any of the specifiers evaluates to true. If definition contains only one specifier,
+    it is evaluated as if it was connected with ".true" keyword by ".and" operator.
+
+    If specifier is a ".true" keyword, it always evaluates to true.
+
+    If specifier is a ".false" keyword, it always evaluates to false. Specifier evaluates to false
+    when it does not evaluate to true.
+
+    Character range specifier is in the form:
+        '<first_character>' - '<second_character>'
+    If specifier is a character range, it evaluates to true if character in the stream is greater
+    or equal to <first_character> and less or equal to <second_character>. In that situation 
+    the stream pointer is advanced to point to next character in the stream. All C-style escape
+    sequences are supported although trigraph sequences are not. The comparisions are performed
+    on 8-bit unsigned integers.
+
+    Character specifier is in the form:
+        '<single_character>'
+    It evaluates to true if the following character range specifier evaluates to true:
+        '<single_character>' - '<single_character>'
+
+    String specifier is in the form:
+        "<string>"
+    Let N be the number of characters in <string>. Let <string>[i] designate i-th character in
+    <string>. Then the string specifier evaluates to true if and only if for i in the range [0, N)
+    the following character specifier evaluates to true:
+        '<string>[i]'
+    If <string>[i] is a quotation mark, '<string>[i]' is replaced with '\<string>[i]'.
+
+    Symbol specifier can be optionally preceded by a ".loop" keyword in the form:
+        .loop <symbol>                  (1)
+    where <symbol> is defined as follows:
+        <symbol> <definition>;          (2)
+    Construction (1) is replaced by the following code:
+        <symbol$1>
+    and declaration (2) is replaced by the following:
+        <symbol$1> <symbol$2> .or .true;
+        <symbol$2> <symbol> .and <symbol$1>;
+        <symbol> <definition>;
+
+    Synek supports also a register mechanizm. User can, in its SYN file, declare a number of
+    registers that can be accessed in the syn body. Each reg has its name and a default value.
+    The register is one byte wide. The C code can change the default value by calling
+    grammar_set_reg8() with grammar id, register name and a new value. As we know, each rule is
+    a sequence of specifiers joined with .and or .or operator. And now each specifier can be
+    prefixed with a condition expression in a form ".if (<reg_name> <operator> <hex_literal>)"
+    where <operator> can be == or !=. If the condition evaluates to false, the specifier
+    evaluates to .false. Otherwise it evalutes to the specifier.
+
+    ESCAPE SEQUENCES
+    ----------------
+
+    Synek supports all escape sequences in character specifiers. The mapping table is listed below.
+    All occurences of the characters in the first column are replaced with the corresponding
+    character in the second column.
+
+        Escape sequence         Represents
+    ------------------------------------------------------------------------------------------------
+        \a                      Bell (alert)
+        \b                      Backspace
+        \f                      Formfeed
+        \n                      New line
+        \r                      Carriage return
+        \t                      Horizontal tab
+        \v                      Vertical tab
+        \'                      Single quotation mark
+        \"                      Double quotation mark
+        \\                      Backslash
+        \?                      Literal question mark
+        \ooo                    ASCII character in octal notation
+        \xhhh                   ASCII character in hexadecimal notation
+    ------------------------------------------------------------------------------------------------
+
+    RAISING ERRORS
+    --------------
+
+    Any specifier can be followed by a special construction that is executed when the specifier
+    evaluates to false. The construction is in the form:
+        .error <ERROR_TEXT>
+    <ERROR_TEXT> is an identifier declared earlier by error text declaration. The declaration is
+    in the form:
+        .errtext <ERROR_TEXT> "<error_desc>"
+    When specifier evaluates to false and this construction is present, parsing is stopped
+    immediately and <error_desc> is returned as a result of parsing. The error position is also
+    returned and it is meant as an offset from the beggining of the stream to the character that
+    was valid so far. Example:
+
+        (**** syntax script ****)
+
+        .syntax program;
+        .errtext MISSING_SEMICOLON      "missing ';'"
+        program         declaration .and .loop space .and ';' .error MISSING_SEMICOLON .and
+                        .loop space .and '\0';
+        declaration     "declare" .and .loop space .and identifier;
+        space           ' ';
+
+        (**** sample code ****)
+
+        declare foo ,
+
+    In the example above checking the sample code will result in error message "missing ';'" and
+    error position 12. The sample code is not correct. Note the presence of '\0' specifier to
+    assure that there is no code after semicolon - only spaces.
+    <error_desc> can optionally contain identifier surrounded by dollar signs $. In such a case,
+    the identifier and dollar signs are replaced by a string retrieved by invoking symbol with
+    the identifier name. The starting position is the error position. The lenght of the resulting
+    string is the position after invoking the symbol.
+
+    PRODUCTION
+    ----------
+
+    Synek not only checks the syntax but it can also produce (emit) bytes associated with specifiers
+    that evaluate to true. That is, every specifier and optional error construction can be followed
+    by a number of emit constructions that are in the form:
+        .emit <parameter>
+    <paramater> can be a HEX number, identifier, a star * or a dollar $. HEX number is preceded by
+    0x or 0X. If <parameter> is an identifier, it must be earlier declared by emit code declaration
+    in the form:
+        .emtcode <identifier> <hex_number>
+
+    When given specifier evaluates to true, all emits associated with the specifier are output
+    in order they were declared. A star means that last-read character should be output instead
+    of constant value. Example:
+
+        (**** syntax script ****)
+
+        .syntax foobar;
+        .emtcode WORD_FOO       0x01
+        .emtcode WORD_BAR       0x02
+        foobar      FOO .emit WORD_FOO .or BAR .emit WORD_BAR .or .true .emit 0x00;
+        FOO         "foo" .and SPACE;
+        BAR         "bar" .and SPACE;
+        SPACE       ' ' .or '\0';
+
+        (**** sample text 1 ****)
+
+        foo
+
+        (**** sample text 2 ****)
+
+        foobar
+
+    For both samples the result will be one-element array. For first sample text it will be
+    value 1, for second - 0. Note that every text will be accepted because of presence of
+    .true as an alternative.
+
+    Another example:
+
+        (**** syntax script ****)
+
+        .syntax declaration;
+        .emtcode VARIABLE       0x01
+        declaration     "declare" .and .loop space .and
+                        identifier .emit VARIABLE .and          (1)
+                        .true .emit 0x00 .and                   (2)
+                        .loop space .and ';';
+        space           ' ' .or '\t';
+        identifier      .loop id_char .emit *;                  (3)
+        id_char         'a'-'z' .or 'A'-'Z' .or '_';
+
+        (**** sample code ****)
+
+        declare    fubar;
+
+    In specifier (1) symbol <identifier> is followed by .emit VARIABLE. If it evaluates to
+    true, VARIABLE constant and then production of the symbol is output. Specifier (2) is used
+    to terminate the string with null to signal when the string ends. Specifier (3) outputs
+    all characters that make declared identifier. The result of sample code will be the
+    following array:
+        { 1, 'f', 'u', 'b', 'a', 'r', 0 }
+
+    If .emit is followed by dollar $, it means that current position should be output. Current
+    position is a 32-bit unsigned integer distance from the very beginning of the parsed string to
+    first character consumed by the specifier associated with the .emit instruction. Current
+    position is stored in the output buffer in Little-Endian convention (the lowest byte comes
+    first).

+ *
+ *
+ * This implementation is "Simplex Noise" as presented by
+ * Ken Perlin at a relatively obscure and not often cited course
+ * session "Real-Time Shading" at Siggraph 2001 (before real
+ * time shading actually took on), under the title "hardware noise".
+ * The 3D function is numerically equivalent to his Java reference
+ * code available in the PDF course notes, although I re-implemented
+ * it from scratch to get more readable code. The 1D, 2D and 4D cases
+ * were implemented from scratch by me from Ken Perlin's text.
+ *
+ * This file has no dependencies on any other file, not even its own
+ * header file. The header file is made for use by external code only.

+ * Permutation table. This is just a random jumble of all numbers 0-255,
+ * repeated twice to avoid wrapping the index at 255 for each lookup.
+ * This needs to be exactly the same for all instances on all platforms,
+ * so it's easiest to just keep it as static explicit data.
+ * This also removes the need for any initialisation of this class.
+ *
+ * Note that making this an int[] instead of a char[] might make the
+ * code run faster on platforms with a high penalty for unaligned single
+ * byte addressing. Intel x86 is generally single-byte-friendly, but
+ * some other CPUs are faster with 4-aligned reads.
+ * However, a char[] is smaller, which avoids cache trashing, and that
+ * is probably the most important aspect on most architectures.
+ * This array is accessed a *lot* by the noise functions.
+ * A vector-valued noise over 3D accesses it 96 times, and a
+ * float-valued 4D noise 64 times. We want this to fit in the cache!

+// One important change in the language is that when a matrix is used
+// as an argument to a matrix constructor, it must be the only argument

+// here we only care to re-introduce constructors for old (square)

+//
+// This file defines nearly all constructors and operators for built-in data
+// types, using extended language syntax. In general, compiler treats
+// constructors and operators as ordinary functions with some exceptions.
+// For example, the language does not allow functions to be called in
+// constant expressions - here the exception is made to allow it.
+//
+// Each implementation provides its own version of this file. Each
+// implementation can define the required set of operators and constructors
+// in its own fashion.
+//
+// The extended language syntax is only present when compiling this file.
+// It is implicitly included at the very beginning of the compiled shader,
+// so no built-in functions can be used.
+//
+// To communicate with the implementation, a special extended "__asm" keyword
+// is used, followed by an instruction name (any valid identifier), a
+// destination variable identifier and a list of zero or more source
+// variable identifiers.
+//
+// A variable identifier is a variable name declared earlier in the code
+// (as a function parameter, local or global variable).
+//
+// An instruction name designates an instruction that must be exported
+// by the implementation.  Each instruction receives data from source
+// variable identifiers and returns data in the destination variable
+// identifier.
+//
+// It is up to the implementation how to define a particular operator
+// or constructor. If it is expected to being used rarely, it can be
+// defined in terms of other operators and constructors,
+// for example:
+//
+// ivec2 __operator + (const ivec2 x, const ivec2 y) {
+//    return ivec2 (x[0] + y[0], x[1] + y[1]);
+// }
+//
+// If a particular operator or constructor is expected to be used very
+// often or is an atomic operation (that is, an operation that cannot be
+// expressed in terms of other operations or would create a dependency
+// cycle) it must be defined using one or more __asm constructs.
+//
+// Each implementation must define constructors for all scalar types
+// (bool, float, int).  There are 9 scalar-to-scalar constructors
+// (including identity constructors). However, since the language
+// introduces special constructors (like matrix constructor with a single
+// scalar value), implementations must also implement these cases.
+// The compiler provides the following algorithm when resolving a constructor:
+// - try to find a constructor with a prototype matching ours,
+// - if no constructor is found and this is a scalar-to-scalar constructor,
+//   raise an error,
+// - if a constructor is found, execute it and return,
+// - count the size of the constructor parameter list - if it is less than
+//   the size of our constructor's type, raise an error,
+// - for each parameter in the list do a recursive constructor matching for
+//   appropriate scalar fields in the constructed variable,
+//
+// Each implementation must also define a set of operators that deal with
+// built-in data types.
+// There are four kinds of operators:
+// 1) Operators that are implemented only by the compiler: "()" (function
+//    call), "," (sequence) and "?:" (selection).
+// 2) Operators that are implemented by the compiler by expressing it in
+//    terms of other operators:
+//    - "." (field selection) - translated to subscript access,
+//    - "&&" (logical and) - translated to "<left_expr> ? <right_expr> :
+//      false",
+//    - "||" (logical or) - translated to "<left_expr> ? true : <right_expr>",
+// 3) Operators that can be defined by the implementation and if the required
+//    prototype is not found, standard behaviour is used:
+//    - "==", "!=", "=" (equality, assignment) - compare or assign
+//      matching fields one-by-one;
+//      note that at least operators for scalar data types must be defined
+//      by the implementation to get it work,
+// 4) All other operators not mentioned above. If no required prototype is
+//    found, an error is raised. An implementation must follow the language
+//    specification to provide all valid operator prototypes.

+ * when modifying or extending this file, several things must be taken into
+ * consideration:
+ *
+ * - when adding new operators that were marked as reserved in the
+ *   initial specification, one must only uncomment particular lines of
+ *   code that refer to operators being added;
+ *
+ * - when adding new shader targets, one must reserve a new value for
+ *   shader_type register and use it in .if constructs for symbols that
+ *   are exclusive for that shader;
+ *
+ * - some symbols mimic output of other symbols - the best example is
+ *   the "for" construct: expression "for (foo(); ; bar())" is seen as
+ *   "for (foo(); true; bar())" by the output processor - hence, special
+ *   care must be taken when rearranging output of essential symbols;
+ *
+ * - order of single-quoted tokens does matter in alternatives - so do not
+ *   parse "<" operator before "<<" and "<<" before "<<=";
+ *
+ * - all double-quoted tokens are internally preprocessed to eliminate
+ *   problems with parsing strings that are prefixes of other strings,
+ *   like "sampler1D" and "sampler1DShadow";

+ * as defined by the OpenGL specification.
+ *
+ * We optimize for the common case used for full-scene antialiasing:
+ *    // start with accum buffer cleared to zero
+ *    glAccum(GL_LOAD, w);   // or GL_ACCUM the first image
+ *    glAccum(GL_ACCUM, w);
+ *    ...
+ *    glAccum(GL_ACCUM, w);
+ *    glAccum(GL_RETURN, 1.0);
+ * That is, we start with an empty accumulation buffer and accumulate
+ * n images, each with weight w = 1/n.
+ * In this scenario, we can simply store unscaled integer values in
+ * the accum buffer instead of scaled integers.  We'll also keep track
+ * of the w value so when we do GL_RETURN we simply divide the accumulated
+ * values by n (n=1/w).
+ * This lets us avoid _many_ int->float->int conversions.

+ * Line Rasterizer Template
+ *
+ * This file is #include'd to generate custom line rasterizers.
+ *
+ * The following macros may be defined to indicate what auxillary information
+ * must be interplated along the line:
+ *    INTERP_Z        - if defined, interpolate Z values
+ *    INTERP_RGBA     - if defined, interpolate RGBA values
+ *    INTERP_INDEX    - if defined, interpolate color index values
+ *    INTERP_ATTRIBS  - if defined, interpolate attribs (texcoords, varying, etc)
+ *
+ * When one can directly address pixels in the color buffer the following
+ * macros can be defined and used to directly compute pixel addresses during
+ * rasterization (see pixelPtr):
+ *    PIXEL_TYPE          - the datatype of a pixel (GLubyte, GLushort, GLuint)
+ *    BYTES_PER_ROW       - number of bytes per row in the color buffer
+ *    PIXEL_ADDRESS(X,Y)  - returns the address of pixel at (X,Y) where
+ *                          Y==0 at bottom of screen and increases upward.
+ *
+ * Similarly, for direct depth buffer access, this type is used for depth
+ * buffer addressing:
+ *    DEPTH_TYPE          - either GLushort or GLuint
+ *
+ * Optionally, one may provide one-time setup code
+ *    SETUP_CODE    - code which is to be executed once per line
+ *
+ * To actually "plot" each pixel the PLOT macro must be defined...
+ *    PLOT(X,Y) - code to plot a pixel.  Example:
+ *                if (Z < *zPtr) {
+ *                   *zPtr = Z;
+ *                   color = pack_rgb( FixedToInt(r0), FixedToInt(g0),
+ *                                     FixedToInt(b0) );
+ *                   put_pixel( X, Y, color );
+ *                }
+ *
+ * This code was designed for the origin to be in the lower-left corner.

+/*
+ * Triangle Rasterizer Template
+ *
+ * This file is #include'd to generate custom triangle rasterizers.
+ *
+ * The following macros may be defined to indicate what auxillary information
+ * must be interpolated across the triangle:
+ *    INTERP_Z        - if defined, interpolate integer Z values
+ *    INTERP_RGB      - if defined, interpolate integer RGB values
+ *    INTERP_ALPHA    - if defined, interpolate integer Alpha values
+ *    INTERP_INDEX    - if defined, interpolate color index values
+ *    INTERP_INT_TEX  - if defined, interpolate integer ST texcoords
+ *                         (fast, simple 2-D texture mapping, without
+ *                         perspective correction)
+ *    INTERP_ATTRIBS  - if defined, interpolate arbitrary attribs (texcoords,
+ *                         varying vars, etc)  This also causes W to be
+ *                         computed for perspective correction).
+ *
+ * When one can directly address pixels in the color buffer the following
+ * macros can be defined and used to compute pixel addresses during
+ * rasterization (see pRow):
+ *    PIXEL_TYPE          - the datatype of a pixel (GLubyte, GLushort, GLuint)
+ *    BYTES_PER_ROW       - number of bytes per row in the color buffer
+ *    PIXEL_ADDRESS(X,Y)  - returns the address of pixel at (X,Y) where
+ *                          Y==0 at bottom of screen and increases upward.
+ *
+ * Similarly, for direct depth buffer access, this type is used for depth
+ * buffer addressing (see zRow):
+ *    DEPTH_TYPE          - either GLushort or GLuint
+ *
+ * Optionally, one may provide one-time setup code per triangle:
+ *    SETUP_CODE    - code which is to be executed once per triangle
+ *
+ * The following macro MUST be defined:
+ *    RENDER_SPAN(span) - code to write a span of pixels.
+ *
+ * This code was designed for the origin to be in the lower-left corner.
+ *
+ * Inspired by triangle rasterizer code written by Allen Akin.  Thanks Allen!
+ *
+ *
+ * Some notes on rasterization accuracy:
+ *
+ * This code uses fixed point arithmetic (the GLfixed type) to iterate
+ * over the triangle edges and interpolate ancillary data (such as Z,
+ * color, secondary color, etc).  The number of fractional bits in
+ * GLfixed and the value of SUB_PIXEL_BITS has a direct bearing on the
+ * accuracy of rasterization.
+ *
+ * If SUB_PIXEL_BITS=4 then we'll snap the vertices to the nearest
+ * 1/16 of a pixel.  If we're walking up a long, nearly vertical edge
+ * (dx=1/16, dy=1024) we'll need 4 + 10 = 14 fractional bits in
+ * GLfixed to walk the edge without error.  If the maximum viewport
+ * height is 4K pixels, then we'll need 4 + 12 = 16 fractional bits.
+ *
+ * Historically, Mesa has used 11 fractional bits in GLfixed, snaps
+ * vertices to 1/16 pixel and allowed a maximum viewport height of 2K
+ * pixels.  11 fractional bits is actually insufficient for accurately
+ * rasterizing some triangles.  More recently, the maximum viewport
+ * height was increased to 4K pixels.  Thus, Mesa should be using 16
+ * fractional bits in GLfixed.  Unfortunately, there may be some issues
+ * with setting FIXED_FRAC_BITS=16, such as multiplication overflow.
+ * This will have to be examined in some detail...
+ *
+ * For now, if you find rasterization errors, particularly with tall,
+ * sliver triangles, try increasing FIXED_FRAC_BITS and/or decreasing
+ * SUB_PIXEL_BITS.

+    * call it a ``major'' edge.  The other two edges are the
+    * ``top'' edge (for the upper subtriangle) and the ``bottom''
+    * edge (for the lower subtriangle).  If either of these two
+    * edges is horizontal or very close to horizontal, the
+    * corresponding subtriangle might cover zero sample points;
+    * we take care to handle such cases, for performance as well
+    * as correctness.
+    *
+    * By stepping rasterization parameters along the major edge,
+    * we can avoid recomputing them at the discontinuity where
+    * the top and bottom edges meet.  However, this forces us to
+    * be able to scan both left-to-right and right-to-left.
+    * Also, we must determine whether the major edge is at the
+    * left or right side of the triangle.  We do this by
+    * computing the magnitude of the cross-product of the major
+    * and top edges.  Since this magnitude depends on the sine of
+    * the angle between the two edges, its sign tells us whether
+    * we turn to the left or to the right when travelling along
+    * the major edge to the top edge, and from this we infer
+    * whether the major edge is on the left or the right.
+    *
+    * Serendipitously, this cross-product magnitude is also a
+    * value we need to compute the iteration parameter
+    * derivatives for the triangle, and it can be used to perform
+    * backface culling because its sign tells us whether the
+    * triangle is clockwise or counterclockwise.  In this code we
+    * refer to it as ``area'' because it's also proportional to
+    * the pixel area of the triangle.

+       * We always sample at pixel centers.  However, we avoid
+       * explicit half-pixel offsets in this code by incorporating
+       * the proper offset in each of x and y during the
+       * transformation to window coordinates.
+       *
+       * We also apply the usual rasterization rules to prevent
+       * cracks and overlaps.  A pixel is considered inside a
+       * subtriangle if it meets all of four conditions: it is on or
+       * to the right of the left edge, strictly to the left of the
+       * right edge, on or below the top edge, and strictly above
+       * the bottom edge.  (Some edges may be degenerate.)
+       *
+       * The following discussion assumes left-to-right scanning
+       * (that is, the major edge is on the left); the right-to-left
+       * case is a straightforward variation.
+       *
+       * We start by finding the half-integral y coordinate that is
+       * at or below the top of the triangle.  This gives us the
+       * first scan line that could possibly contain pixels that are
+       * inside the triangle.
+       *
+       * Next we creep down the major edge until we reach that y,
+       * and compute the corresponding x coordinate on the edge.
+       * Then we find the half-integral x that lies on or just
+       * inside the edge.  This is the first pixel that might lie in
+       * the interior of the triangle.  (We won't know for sure
+       * until we check the other edges.)
+       *
+       * As we rasterize the triangle, we'll step down the major
+       * edge.  For each step in y, we'll move an integer number
+       * of steps in x.  There are two possible x step sizes, which
+       * we'll call the ``inner'' step (guaranteed to land on the
+       * edge or inside it) and the ``outer'' step (guaranteed to
+       * land on the edge or outside it).  The inner and outer steps
+       * differ by one.  During rasterization we maintain an error
+       * term that indicates our distance from the true edge, and
+       * select either the inner step or the outer step, whichever
+       * gets us to the first pixel that falls inside the triangle.
+       *
+       * All parameters (z, red, etc.) as well as the buffer
+       * addresses for color and z have inner and outer step values,
+       * so that we can increment them appropriately.  This method
+       * eliminates the need to adjust parameters by creeping a
+       * sub-pixel amount into the triangle at each scanline.

+ * \struct SWvertex
+ * \brief Data-structure to handle vertices in the software rasterizer.
+ * 
+ * The software rasterizer now uses this format for vertices.  Thus a
+ * 'RasterSetup' stage or other translation is required between the
+ * tnl module and the swrast rasterization functions.  This serves to
+ * isolate the swrast module from the internals of the tnl module, and
+ * improve its usefulness as a fallback mechanism for hardware
+ * drivers.
+ *
+ * wpos = attr[FRAG_ATTRIB_WPOS] and MUST BE THE FIRST values in the
+ * vertex because of the tnl clipping code.
+
+ * wpos[0] and [1] are the screen-coords of SWvertex.
+ * wpos[2] is the z-buffer coord (if 16-bit Z buffer, in range [0,65535]).
+ * wpos[3] is 1/w where w is the clip-space W coord.  This is the value
+ * that clip{XYZ} were multiplied by to get ndc{XYZ}.
+ *
+ * Full software drivers:
+ *   - Register the rastersetup and triangle functions from
+ *     utils/software_helper.
+ *   - On statechange, update the rasterization pointers in that module.
+ *
+ * Rasterization hardware drivers:
+ *   - Keep native rastersetup.
+ *   - Implement native twoside,offset and unfilled triangle setup.
+ *   - Implement a translator from native vertices to swrast vertices.
+ *   - On partial fallback (mix of accelerated and unaccelerated
+ *   prims), call a pass-through function which translates native
+ *   vertices to SWvertices and calls the appropriate swrast function.
+ *   - On total fallback (vertex format insufficient for state or all
+ *     primitives unaccelerated), hook in swrast_setup instead.

+ * \mainpage The TNL-module
+ *
+ * TNL stands for "transform and lighting", i.e. this module implements
+ * a pipeline that receives as input a buffer of vertices and does all
+ * necessary transformations (rotations, clipping, vertex shader etc.)
+ * and passes then the output to the rasterizer.
+ *
+ * The tnl_pipeline contains the array of all stages, which should be
+ * applied. Each stage is a black-box, which is described by an
+ * tnl_pipeline_stage. The function ::_tnl_run_pipeline applies all the
+ * stages to the vertex_buffer TNLcontext::vb, where the vertex data
+ * is stored. The last stage in the pipeline is the rasterizer.

+ * and should be left intact.
+ *
+ * To customize the pipeline, consider:
+ *
+ * - removing redundant stages (making sure that the software rasterizer
+ *   can cope with this on fallback paths).  An example is fog
+ *   coordinate generation, which is not required in the FX driver.
+ *
+ * - replacing general-purpose machine-independent stages with
+ *   general-purpose machine-specific stages.  There is no example of
+ *   this to date, though it must be borne in mind that all subsequent
+ *   stages that reference the output of the new stage must cope with
+ *   any machine-specific data introduced.  This may not be easy
+ *   unless there are no such stages (ie the new stage is the last in
+ *   the pipe).
+ *

+ * in GL vertex buffer objects (VBOs), and translates all drawing

+ *
+ * The module captures both immediate mode and display list drawing,
+ * and manages the allocation, reference counting and deallocation of
+ * vertex buffer objects itself.
+ * 
+ * The DrawPrimitives() callback can be either implemented by the
+ * driver itself or hooked to the tnl module's _tnl_draw_primitives()
+ * function for hardware without tnl capablilties or during fallbacks.

+    * Unless the vertex arrays are all in a VBO (or locked as with

+    * 1) Do nothing, everything is in a VBO and is processed once
+    *       only.
+    *
