If I understand the randrproto correctly, randr sprite transform happen
after the input device rotation and are somewhat connected to the CRTC
transformation.

Do they solve the case of "this hardware has a sensor offset of 36 degrees
counterclockwise, so we need to rotate any input by this amount"?
