Launcher home screen rotation now works with fixed
transform. When using Quickstep while holding
the phone from an orientation different than
the orientation of the touch, the overview
shown will be that of the phone orientation,
not the touch orientation.
Easier to see this be quickswitching from
portrait to landscape app, turning phone, then
going to overview from the original region you
swiped.

to various rotations to test.
