10. Polygon Rasterization
-All polygons must be convex. Rendering of concave polygons is unspecified
+Render provides only two kinds of polygons, trapezoids and triangles. To
+improve efficiency, several different wire encodings exist for each.

+All trapezoids must be convex. Rendering of concave trapezoids is unspecified
except that the result must obey the clipping rules.
-Each polygon request fills the region closed by the specified path. The
-path is automatically closed if the last point does not coincide with the
-first point.
-
-A point is infinitely small and the path is an infinitely thin line. A
-pixel is inside if the center point of the pixel is inside and the center
-point is not on the boundary. If the center point is on the boundary, the
-pixel is inside if and only if the polygon interior is immediately to its
-right (x increasing direction). Pixels with centers along a horizontal edge
-are a special case and are inside if and only if the polygon interior is
-immediately below (y increasing direction). A polygon contains a pixel if
-the pixel is inside the polygon.

+Rasterization
+Alpha values are generated by point sampling the coverage of a square

-This needs rewriting to match current trapezoid specification and
-base other polygons on that. I suspect imprecise polygons will need

+In Precise poly mode, the sample points are located in a regular grid. When
+alpha depth 'e' is even, the regular grid is 2**(e/2) + 1 samples wide and
+2**(e/2) -1 samples high. For odd alpha depth 'o', the sample grid is 2**o
+- 1 samples wide and 1 sample high. Note that odd alpha depth usually
+occurs only at depth 1, so this misshapen sample grid has no ill effects.
+The sample grid is centered within the pixel and then each sample point is
+rounded down to a point on the sub-pixel coordinate grid.
