Subject: Improve scrolling by performing styling in methods called before
 drawing instead of inside drawing which then caused the drawing to be
 abandoned, and black blocks to appear on-screen. Discard responsive scrolling
 overdraw when that overdrawn content is invalid. Style just the visible area
 instead of the whole document when styling changes run beyond painting area.
