Ported ProceduralTexturePhysics demo to ARB_vertex_program and

ARB_fragment_program from NV_vertex_program, NV_register_combiners and
NV_texture_shader for compatibility with all vendors' graphics cards.
Tested resulting demo on both NVidia and ATI cards. Framerate on
Quadro FX Go700 is close to original version after optimization of a
few of the fragment programs. Results are visually similar to (though
probably not identical to) the original version.
