------- Additional Comments from Jocelyn Turcotte <jocelyn.turcotte at nokia.com>
Updated patch after rebasing and splitting the LayerTransform part into bug
#76291.
Another patch will follow up to do a projection of the visible rect instead of
mapping it like collectVisibleContentsRects was doing.
