shell-util: Do not scale the clip in get_content_for_window_actor()

Browse Source 
This is now handled in Mutter. Also, respect the result size instead
of assuming it to be equal to the clip size, as the clip takes actor
coordinates while the result takes buffer coordinates.

This can be fixed in a future API iteration.
