+ * This file contains the implementations of all the XMesa* functions.
+ *
+ *
+ * NOTES:
+ *
+ * The window coordinate system origin (0,0) is in the lower-left corner
+ * of the window.  X11's window coordinate origin is in the upper-left
+ * corner of the window.  Therefore, most drawing functions in this
+ * file have to flip Y coordinates.
+ *
+ * Define USE_XSHM in the Makefile with -DUSE_XSHM if you want to compile
+ * in support for the MIT Shared Memory extension.  If enabled, when you
+ * use an Ximage for the back buffer in double buffered mode, the "swap"
+ * operation will be faster.  You must also link with -lXext.
+ *
+ * Byte swapping:  If the Mesa host and the X display use a different
+ * byte order then there's some trickiness to be aware of when using
+ * XImages.  The byte ordering used for the XImage is that of the X
+ * display, not the Mesa host.
+ * The color-to-pixel encoding for True/DirectColor must be done
+ * according to the display's visual red_mask, green_mask, and blue_mask.
+ * If XPutPixel is used to put a pixel into an XImage then XPutPixel will
+ * do byte swapping if needed.  If one wants to directly "poke" the pixel
+ * into the XImage's buffer then the pixel must be byte swapped first.  In
+ * Mesa, when byte swapping is needed we use the PF_TRUECOLOR pixel format
+ * and use XPutPixel everywhere except in the implementation of
+ * glClear(GL_COLOR_BUFFER_BIT).  We want this function to be fast so
+ * instead of using XPutPixel we "poke" our values after byte-swapping
+ * the clear pixel value if needed.

+ *   2. as horizontal spans (polygons, images) vs random locations (points,
+ *      lines)
+ *   3. different color per-pixel or same color for all pixels
+ *
+ * Furthermore, the X driver needs to support rendering to 3 possible
+ * "buffers", usually one, but sometimes two at a time:
+ *   1. The front buffer as an X window
+ *   2. The back buffer as a Pixmap
+ *   3. The back buffer as an XImage
+ *
+ * Finally, if the back buffer is an XImage, we can avoid using XPutPixel and
+ * optimize common cases such as 24-bit and 8-bit modes.
+ *
+ * By multiplication, there's at least 48 possible combinations of the above.
+ *
+ * Below are implementations of the most commonly used combinations.  They are
+ * accessed through function pointers which get initialized here and are used
+ * directly from the Mesa library.  The 8 function pointers directly correspond
+ * to the first 3 cases listed above.
+ *
+ *
+ * The function naming convention is:
+ *
+ *   [put|get]_[mono]_[row|values]_[format]_[pixmap|ximage]
+ *
+ * New functions optimized for specific cases can be added without too much
+ * trouble.  An example might be the 24-bit TrueColor mode 8A8R8G8B which is
+ * found on IBM RS/6000 X servers.

+ * 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.

+ * This file is a template which generates the OpenGL API entry point
+ * functions.  It should be included by a .c file which first defines
+ * the following macros:
+ *   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 KEYWORD1
+ *   #define KEYWORD2
+ *   #define NAME(func)  gl##func
+ *   #define DISPATCH(func, args, msg)                           \
+ *          struct _glapi_table *dispatch = CurrentDispatch;     \
+ *          (*dispatch->func) args

+ * Mesa context/visual/framebuffer management functions.
+ *
+ * There are three Mesa data types 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.

+/**
+ * \file imports.c
+ * Standard C library function wrappers.
+ * 
+ * Imports are services which the device driver or window system or
+ * operating system provides to the core renderer.  The core renderer (Mesa)
+ * will call these functions in order to do memory allocation, simple I/O,
+ * etc.
+ *
+ * Some drivers will want to override/replace this file with something
+ * specialized, but that'll be rare.
+ *
+ * Eventually, I want to move roll the glheader.h file into this.
+ *
+ * The OpenGL SI's __GLimports structure allows per-context specification of
+ * replacements for the standard C lib functions.  In practice that's probably
+ * never needed; compile-time replacements are far more likely.
+ *
+ * The _mesa_*() functions defined here don't in general take a context
+ * parameter.  I guess we can change that someday, if need be.
+ * So for now, the __GLimports stuff really isn't used.
+ *
+ * \todo Functions still needed:
+ * - scanf
+ * - qsort
+ * - bsearch
+ * - rand and RAND_MAX
+ *
+ * \note When compiled into a XFree86 module these functions wrap around
+ * XFree86 own wrappers.

+
+         This isn't a bad approximation of 1/sqrt.  The maximum difference from

+         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:

+
+         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

+ * Horner scheme for Bezier curves
+ *
+ * Bezier curves can be computed via a Horner scheme.
+ * Horner is numerically less stable than the de Casteljau
+ * algorithm, but it is faster. For curves of degree n
+ * the complexity of Horner is O(n) and de Casteljau is O(n^2).
+ * Since stability is not important for displaying curve
+ * points I decided to use the Horner scheme.
+ *
+ * A cubic Bezier curve with control points b0, b1, b2, b3 can be
+ * written as
+ *
+ *        (([3]        [3]     )     [3]       )     [3]
+ * c(t) = (([0]*s*b0 + [1]*t*b1)*s + [2]*t^2*b2)*s + [3]*t^2*b3
+ *
+ *                                           [n]
+ * where s=1-t and the binomial coefficients [i]. These can
+ * be computed iteratively using the identity:
+ *
+ * [n]               [n  ]             [n]
+ * [i] = (n-i+1)/i * [i-1]     and     [0] = 1

+ * Horner scheme for Bezier curves
+ *
+ * Bezier curves can be computed via a Horner scheme.
+ * Horner is numerically less stable than the de Casteljau
+ * algorithm, but it is faster. For curves of degree n
+ * the complexity of Horner is O(n) and de Casteljau is O(n^2).
+ * Since stability is not important for displaying curve
+ * points I decided to use the Horner scheme.
+ *
+ * A cubic Bezier curve with control points b0, b1, b2, b3 can be
+ * written as
+ *
+ *        (([3]        [3]     )     [3]       )     [3]
+ * c(t) = (([0]*s*b0 + [1]*t*b1)*s + [2]*t^2*b2)*s + [3]*t^2*b3
+ *
+ *                                           [n]
+ * where s=1-t and the binomial coefficients [i]. These can
+ * be computed iteratively using the identity:
+ *
+ * [n]               [n  ]             [n]
+ * [i] = (n-i+1)/i * [i-1]     and     [0] = 1

+       *  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.

+/* KW: Clip functions now do projective divide as well.  The projected
+ * 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
+ * automatically available.

+/* TODO:
+ *    Fragment Program Stuff:
+ *    -----------------------------------------------------
+ *
+ *    - things from Michal's email
+ *       + overflow on atoi
+ *       + not-overflowing floats (don't use parse_integer..)
+ *       + can remove range checking in arbparse.c
+ *
+ *    - check all limits of number of various variables
+ *      + parameters
+ *
+ *    - test! test! test!
+ *
+ *    Vertex Program Stuff:
+ *    -----------------------------------------------------
+ *    - Optimize param array usage and count limits correctly, see spec,
+ *         section 2.14.3.7
+ *       + Record if an array is reference absolutly or relatively (or both)
+ *       + For absolute arrays, store a bitmap of accesses
+ *       + For single parameters, store an access flag
+ *       + After parsing, make a parameter cleanup and merging pass, where
+ *           relative arrays are layed out first, followed by abs arrays, and
+ *           finally single state.
+ *       + Remap offsets for param src and dst registers
+ *       + Now we can properly count parameter usage
+ *
+ *    - Multiple state binding errors in param arrays (see spec, just before
+ *         section 2.14.3.3)
+ *    - grep for XXX
+ *
+ *    Mesa Stuff
+ *    -----------------------------------------------------
+ *    - User clipping planes vs. PositionInvariant
+ *    - Is it sufficient to just multiply by the mvp to transform in the
+ *        PositionInvariant case? Or do we need something more involved?
+ *
+ *    - vp_src swizzle is GLubyte, fp_src swizzle is GLuint
+ *    - fetch state listed in program_parameters list
+ *       + WTF should this go???
+ *       + currently in nvvertexec.c and s_nvfragprog.c
+ *
+ *    - allow for multiple address registers (and fetch address regs properly)
+ *
+ *    Cosmetic Stuff
+ *    -----------------------------------------------------
+ * 	- remove any leftover unused grammar.c stuff (dict_ ?)
+ * 	- fix grammar.c error handling so its not static
+ * 	- #ifdef around stuff pertaining to extentions
+ *
+ *    Outstanding Questions:
+ *    -----------------------------------------------------
+ *    - ARB_matrix_palette / ARB_vertex_blend -- not supported
+ *      what gets hacked off because of this:
+ *       + VERTEX_ATTRIB_MATRIXINDEX
+ *       + VERTEX_ATTRIB_WEIGHT
+ *       + MATRIX_MODELVIEW
+ *       + MATRIX_PALETTE
+ *
+ *    - When can we fetch env/local params from their own register files, and
+ *      when to we have to fetch them into the main state register file?
+ *      (think arrays)
+ *
+ *    Grammar Changes:
+ *    -----------------------------------------------------
+ */

+    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).

+Thoughts on vertex program optimization:
+
+The obvious thing to do is to compile the vertex program into X86/SSE/3DNow!
+assembly code.  That will probably be a lot of work.
+
+Another approach might be to replace the vp_instruction->Opcode field with
+a pointer to a specialized C function which executes the instruction.
+In particular we can write functions which skip swizzling, negating,
+masking, relative addressing, etc. when they're not needed.
+
+For example:
+
+void simple_add( struct vp_instruction *inst )
+{
+   GLfloat *sum = machine->Registers[inst->DstReg.Register];
+   GLfloat *a = machine->Registers[inst->SrcReg[0].Register];
+   GLfloat *b = machine->Registers[inst->SrcReg[1].Register];
+   sum[0] = a[0] + b[0];
+   sum[1] = a[1] + b[1];
+   sum[2] = a[2] + b[2];
+   sum[3] = a[3] + b[3];
+}
+
+*/
+
+/*
+
+KW:
+
+A first step would be to 'vectorize' the programs in the same way as
+the normal transformation code in the tnl module.  Thus each opcode
+takes zero or more input vectors (registers) and produces one or more
+output vectors.
+
+These operations would intially be coded in C, with machine-specific
+assembly following, as is currently the case for matrix
+transformations in the math/ directory.  The preprocessing scheme for
+selecting simpler operations Brian describes above would also work
+here.
+
+This should give reasonable performance without excessive effort.

+ * Accumulation buffer notes
+ *
+ * Normally, accumulation buffer values are GLshorts with values in
+ * [-32767, 32767] which represent floating point colors in [-1, 1],
+ * 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.

+ * We can either specify a base/step to indicate interpolated values, or
+ * fill in arrays of values.  The interpMask and arrayMask bitfields
+ * indicate which are active.
+ *
+ * With this structure it's easy to hand-off span rasterization to
+ * subroutines instead of doing it all inline in the triangle functions
+ * like we used to do.
+ * It also cleans up the local variable namespace a great deal.
+ *
+ * It would be interesting to experiment with multiprocessor rasterization
+ * with this structure.  The triangle rasterizer could simply emit a
+ * stream of these structures which would be consumed by one or more
+ * span-processing threads which could run in parallel.

+ * 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_FOG      - if defined, interpolate FOG values
+ *    INTERP_RGBA     - if defined, interpolate RGBA values
+ *    INTERP_SPEC     - if defined, interpolate specular RGB values
+ *    INTERP_INDEX    - if defined, interpolate color index values
+ *    INTERP_TEX      - if defined, interpolate unit 0 texcoords
+ *    INTERP_MULTITEX - if defined, interpolate multi-texcoords
+ *
+ * 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 interplated across the triangle:
+ *    INTERP_Z        - if defined, interpolate vertex Z values
+ *    INTERP_W        - if defined, interpolate vertex W values
+ *    INTERP_FOG      - if defined, interpolate fog values
+ *    INTERP_RGB      - if defined, interpolate RGB values
+ *    INTERP_ALPHA    - if defined, interpolate Alpha values (req's INTERP_RGB)
+ *    INTERP_SPEC     - if defined, interpolate specular RGB values
+ *    INTERP_INDEX    - if defined, interpolate color index values
+ *    INTERP_INT_TEX  - if defined, interpolate integer ST texcoords
+ *                         (fast, simple 2-D texture mapping)
+ *    INTERP_TEX      - if defined, interpolate set 0 float STRQ texcoords
+ *                         NOTE:  OpenGL STRQ = Mesa STUV (R was taken for red)
+ *    INTERP_MULTITEX - if defined, interpolate N units of STRQ texcoords
+ *
+ * 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:
+ *    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
+ *    CLEANUP_CODE    - code to execute at end of 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.

+    * Conceptually, we view a triangle as two subtriangles

+    * intersected by this line is one with maximal absolute dy; we
+    * 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.
+ *
+ * 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.
+ *
+ * The initial vertex_buffer data may either come from an ::immediate
+ * structure or client vertex_arrays or display lists:
+ *
+ *
+ * - The ::immediate structure records all the GL commands issued between
+ * glBegin and glEnd.  \n
+ * The structure accumulates data, until it is either full or it is
+ * flushed (usually by a state change). Before starting then the pipeline,
+ * the collected vertex data in ::immediate has to be pushed into
+ * TNLcontext::vb.
+ * This happens in ::_tnl_vb_bind_immediate. The pipeline is then run by
+ * calling tnl_device_driver::RunPipeline = ::_tnl_run_pipeline, which
+ * is stored in TNLcontext::Driver.   \n
+ * An ::immediate does (for performance reasons) usually not finish with a
+ * glEnd, and hence it also does not need to start with a glBegin.
+ * This means that the last vertices of one ::immediate may need to be
+ * saved for the next one.
+ *
+ *
+ * - NOT SURE ABOUT THIS: The vertex_arrays structure is used to handle
+ * glDrawArrays etc.  \n
+ * Here, the data of the vertex_arrays is copied by ::_tnl_vb_bind_arrays
+ * into TNLcontext::vb, so that the pipeline can be started.

+ * 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).
+ *
+ * - inserting optimized (but specialized) stages ahead of the
+ *   general-purpose fallback implementation.  For example, the old
+ *   fastpath mechanism, which only works when the VB->Elts input is
+ *   available, can be duplicated by placing the fastpath stage at the
+ *   head of this pipeline.  Such specialized stages are currently
+ *   constrained to have no outputs (ie. they must either finish the *
+ *   pipeline by returning GL_FALSE from run(), or do nothing).
+ *
+ * Some work can be done to lift some of the restrictions in the final
+ * case, if it becomes necessary to do so.

+/* Display list compiler attempts to store lists of vertices with the
+ * same vertex layout.  Additionally it attempts to minimize the need
+ * for execute-time fixup of these vertex lists, allowing them to be
+ * cached on hardware.
+ *
+ * There are still some circumstances where this can be thwarted, for
+ * example by building a list that consists of one very long primitive
+ * (eg Begin(Triangles), 1000 vertices, End), and calling that list
+ * from inside a different begin/end object (Begin(Lines), CallList,
+ * End).  
+ *
+ * In that case the code will have to replay the list as individual
+ * commands through the Exec dispatch table, or fix up the copied
+ * vertices at execute-time.
+ *
+ * The other case where fixup is required is when a vertex attribute
+ * is introduced in the middle of a primitive.  Eg:
+ *  Begin(Lines)
+ *  TexCoord1f()           Vertex2f()
+ *  TexCoord1f() Color3f() Vertex2f()
+ *  End()
+ *
+ *  If the current value of Color isn't known at compile-time, this
+ *  primitive will require fixup.
+ *
+ *
+ * The list compiler currently doesn't attempt to compile lists
+ * containing EvalCoord or EvalPoint commands.  On encountering one of
+ * these, compilation falls back to opcodes.  
+ *
+ * This could be improved to fallback only when a mix of EvalCoord and
+ * Vertex commands are issued within a single primitive.
