I'm dubious about handling things this way...
If I understand his proposal, it is almost identical to the "scaler"
proposal.
Right now if a hi-def output has a scale of 2, the client aware of this
draws the buffer twice as large and sends a scale of 2 to his api. I
believe the identical behavior is achieved by sending a scale of 1/2 to
the proposed scaler api. This includes how event positions are handled.
So I think the proposal can be shorted down to this:
1. Add a scale to the outputs. This goes along with the output transform
which specifies 90 degree rotations/reflections.
2. Clients that want to draw hi-res surfaces to match the output use the
scaler api to apply the inverse scale to their surfaces.
