* In scan converting polygons, we want to choose those pixels
* which are inside the polygon. Thus, we add .5 to the starting
* x coordinate for both left and right edges. Now we choose the
* first pixel which is inside the pgon for the left edge and the
* first pixel which is outside the pgon for the right edge.
* Draw the left pixel, but not the right.
*
* How to add .5 to the starting x coordinate:
* If the edge is moving to the right, then subtract dy from the
* error term from the general form of the algorithm.
* If the edge is moving to the left, then add dy to the error term.
*
* The reason for the difference between edges moving to the left
* and edges moving to the right is simple: If an edge is moving
* to the right, then we want the algorithm to flip immediately.
* If it is moving to the left, then we don't want it to flip until
* we traverse an entire pixel.

* 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).
