                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
                coords                                                                              */
