  Remove uniform memory copy from GL front-end.
  
  This moves the uniform query to the back-end. In D3D, this requires
  a bit more redesign, especially for matrix uniforms.
  
  Gives about a 10% speed improvement in the GL/NULL uniforms stress
  test on Windows (UniformsBenchmark.Run/gl_null_400_vec4).
