// Example:
// User shader flags Matrices in the Vertex Program:
// -> When rendering with a material, the driver will call setUniformDriver,
// which will check if the flag Matrices exists, and if so, it will use
// the index cache to find which matrices are needed by the shader,

// This does not work extremely efficient, but it's the most practical option
// for passing builtin parameters onto user provided shaders.
// Note: May need additional flags related to scene sorting, etcetera.
