Just trying to get better perf coverage of our mipmapping code, in
anticipation of different optimization strategies for the sRGB case.
I want to have some good reference points to measure progress.

Need some data to inform a decision about always doing gamma correct
mipmapping.

This is much more explicit about what that type represents (are we in
legacy mode or not), which also makes it suitable for other (upcoming)
usage.

GLBenches do not expect gl state to change between onPerCanvasPreDraw and *PostDraw, but we do a clear and sometimes we clear as draw. This causes us to bind vertex objects / programs / etc.
This change creates two new virtual methods which are called right before and immediately after timing.
