+ *     fill.h
+ *
+ *     Created by Brian Kelleher; Oct 1985
+ *
+ *     Include file for filled polygon routines.
+ *
+ *     These are the data structures needed to scan
+ *     convert regions.  Two different scan conversion
+ *     methods are available -- the even-odd method, and
+ *     the winding number method.
+ *     The even-odd rule states that a point is inside
+ *     the polygon if a ray drawn from that point in any
+ *     direction will pass through an odd number of
+ *     path segments.
+ *     By the winding number rule, a point is decided
+ *     to be inside the polygon if a ray drawn from that
+ *     point in any direction passes through a different
+ *     number of clockwise and counter-clockwise path
+ *     segments.
+ *
+ *     These data structures are adapted somewhat from
+ *     the algorithm in (Foley/Van Dam) for scan converting
+ *     polygons.
+ *     The basic algorithm is to start at the top (smallest y)
+ *     of the polygon, stepping down to the bottom of
+ *     the polygon by incrementing the y coordinate.  We
+ *     keep a list of edges which the current scanline crosses,
+ *     sorted by x.  This list is called the Active Edge Table (AET)
+ *     As we change the y-coordinate, we update each entry in 
+ *     in the active edge table to reflect the edges new xcoord.
+ *     This list must be sorted at each scanline in case
+ *     two edges intersect.
+ *     We also keep a data structure known as the Edge Table (ET),
+ *     which keeps track of all the edges which the current
+ *     scanline has not yet reached.  The ET is basically a
+ *     list of ScanLineList structures containing a list of
+ *     edges which are entered at a given scanline.  There is one
+ *     ScanLineList per scanline at which an edge is entered.
+ *     When we enter a new edge, we move it from the ET to the AET.
+ *
+ *     From the AET, we can implement the even-odd rule as in
+ *     (Foley/Van Dam).
+ *     The winding number rule is a little trickier.  We also
+ *     keep the EdgeTableEntries in the AET linked by the
+ *     nextWETE (winding EdgeTableEntry) link.  This allows
+ *     the edges to be linked just as before for updating
+ *     purposes, but only uses the edges linked by the nextWETE
+ *     link as edges representing spans of the polygon to
+ *     drawn (as with the even-odd rule).
