 * Multi-purpose OGL material.
 *
 * Generally, the idea is that a Program contains uniforms but
 * a material sets them, using the standard parameters of Graphics::Material
 * or whatever necessary to achieve an effect
 *
 * Programs are owned by the renderer, since they are shared between materials.
