Subject: Remove demos that have moved to
 git+ssh://git.freedesktop.org/git/mesa/demos.

The remaining programs are ones I've had difficulty finding a build
environment for to make the build system or are unit tests that should
probably live next to their code instead.  Hopefully people can bring
over the build for remaining pieces they care about.

-/**
- * 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.
