Set frame rate GTE to Max for MRR

For animation, scroll/fling, and other velocity, the frame rate might
change after start, which can be specified with GTE setFrameRate.
However changing display refresh rate on an MRR
device will jank, so the stand-in solution is to equate GTE votes to Max
for MRR.
