We scale the input region by output_scale / buffer_scale ... so if you have
buffer_scale of 1 and output scale of 2 it gets scaled up by 2.
If the app sets buffer scale to 2 it gets scaled by 1 (i.e not at all) because
the app is supposed to be rendering at the correct resolution.
Also is it really "the upper half" or the the "upper left quarter" ?
We always scale the opaque region by the buffer scale which looks wrong ...
unfortunately can't test it right now does something like this work? :
