-/**
- * Test for exact point/line/polygon rasterization, or at least rasterization
- * that fits the tolerance of the OpenGL spec.
- *
- * Brian Paul
- * 9 Nov 2007
- */
-
-/*
- * Notes:
- * - 'm' to cycle through point, hline, vline and quad drawing
- * - Use cursor keys to translate coordinates (z to reset)
- * - Resize window to check for proper rasterization
- * - Make sure your LCD is running in its native resolution
- *   
- * If translation is (0,0):
- *  a point will be drawn where x%2==0 and y%2==0,
- *  a horizontal line will be drawn where x%2==0,
- *  a vertical line will be drawn where y%2==0,
- *  for quads, pixels will be set where (x%4)!=3 and (y%4)!=3
- *
- * XXX todo: do glReadPixels and test that the results are what's expected.
- * Upon failure, iterate over sub-pixel translations to find the ideal offset.
