The current implementation of OS compositor surfaces always repaints the entire surface if anything changes in it.
Instead, we should give webrender::compositor::bind an update rect parameter so that we can save the overhead from touching unchanged pixels.

Maybe use a region instead of a rectangle? Just as side note.

This passes the existing dirty rect for a picture cache update
through the native compositor interface, allowing compositors
to only update a sub-rect of a tile.
Also update the example to pass dirty rect to DirectComposition,
and add debug drawing for compositor redraw region.
