Add an extra change hint, UpdateOverflow, that can be used to specify that a frame's overflow areas may have changed and that they need to be recalculated. When a transform on a frame changes, instead of marking it for reflow, set this hint instead. There is an added virtual function on nsIFrame, UpdateOverflow, which is called recursively on a frame when the corresponding hint is set, to allow it to update its overflow areas.
