Get rid of glMatrixMode calls

With the explicit calls we don't need to worry about current state
outside of the GPU module now. In fact. we don't need to worry about
current matrix mode in core profile at all.

Legacy OpenGL now has some code which ensures current matrix mode
when using explicit calls to push/pop matrix.
