Now that we are passing the bone matrices to the skinning shader as a texture, the skinning demos are not working on older, simpler graphics cards generating the following error

"Too many vertex shader texture samplers"

The solution would be to provide an OpenGL 1.4 compatible shader that does not use vertex texture samplers, but uses uniforms instead. This is not trivial, because it would mean handing the uploading of the uniform values in multiple ways. Uniforms and Textures.
