The damage region can be useful to optimize the "resolve" step that we have on
imx6q (GC2000) because there isn't any tiling compatible with both render and
scanout or an any GPU when scanning out a linear buffer since we don't support
linear PE.
This improves fps for e.g `weston-simple-egl` by factor 2 (~30 fps -> ~60 fps).
