--- Comment #17 from Stefan Dösinger stefandoesinger@gmx.at 2008-05-26 03:40:21 --- I think the remapping is mapping the GLSL name strings like "VC12" to a numeric uniform slot in the linked shader program to pass to glLoadUniform. Since we're only using the GLSL name in this case(in the shader itself) and never set a Uniform, we do not need this here I think.
