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.

-/*
- * This program demonstrates how to do "off-screen" rendering using
- * the GLX pixel buffer extension.
- *
- * Written by Brian Paul for the "OpenGL and Window System Integration"
- * course presented at SIGGRAPH '97.  Updated on 5 October 2002.
- *
- * Updated on 31 January 2004 to use native GLX by
- * Andrew P. Lentvorski, Jr. <[email protected]>
- *
- * Usage:
- *   glxpbdemo width height imgfile
- * Where:
- *   width is the width, in pixels, of the image to generate.
- *   height is the height, in pixels, of the image to generate.
- *   imgfile is the name of the PPM image file to write.
- *
- *
- * This demo draws 3-D boxes with random orientation.
- *
- * On machines such as the SGI Indigo you may have to reconfigure your
- * display/X server to enable pbuffers.  Look in the /usr/gfx/ucode/MGRAS/vof/
- * directory for display configurations with the _pbuf suffix.  Use
- * setmon -x <vof> to configure your X server and display for pbuffers.
- *
- * O2 systems seem to support pbuffers well.
