From 68fc4b415e322f6744299e39864fbc377c6eff74 Mon Sep 17 00:00:00 2001

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.
