2. Texture coordinates s, t, and r are divided by q during the rasterization
of points, pixel rectangles, and bitmaps. This division was documented
only for lines and polygons in the 1.0 version. </quote>
I interpret this as we can implement projected transforms in slow vertex mode
by moving the last coord to the 'q' coord and using one less dimension. The only
way to do it in TexCoordPtr would be to massage the data stream to insert extra
