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.

- * fogcoord.c

- * This program demonstrates the use of explicit fog
- * coordinates. You can press the keyboard and change
- * the fog coordinate value at any vertex. You can
- * also switch between using explicit fog coordinates
- * and the default fog generation mode.
- *
- * Pressing the 'f' and 'b' keys move the viewer forward
- * and backwards.
- * Pressing 'c' initiates the default fog generation.
- * Pressing capital 'C' restores explicit fog coordinates.
- * Pressing '1', '2', '3', '8', '9', and '0' add or
- * subtract from the fog coordinate values at one of the
- * three vertices of the triangle.
