  [UI-side compositing] Resizing window doesn't cause scrollbars to show/change size

Reviewed by Simon Fraser.

Hook up ScrollerMac to UI-process resize events so that scrollbars
dynamically resize when resizing window. We should also consider subclassing
ScrollerMac under ScrollbarsControllerMac so we dont duplicate this
NScrollerImp interaction code.
