Usually the RedDrawable bbox dimensions match the src_area dimensions
so that checking that the bbox matches the stream's original dest_area
should be enough to determine if sized stream support is needed to
send the frame.
But making the bbox different could be used to have the scaling be
performed on the client side. So it's better not to assume the bbox and
src_area have the same dimensions.
