Widgets: Use accelerated scroll when scrolled widget is overlapped
Get region of overlapped widgets and scroll only non-overlapped parts of image. Next, schedule an update for overlapped widgets region. This patch improves scrolling performance when scrolled widget has overlapped widgets. Common use cases: - faster scrolling when using "StyleHint::SH_ScrollBar_Transient", - faster scrolling of zoomed image with semi-transparent thumbnail. Accelerated scrolling with overlapped widgets is not available when scale factor is non-integer.
