◆ requestUpdateOutline()

void KisToolPaint::requestUpdateOutline	(	const QPointF &	outlineDocPoint,
		const KoPointerEvent *	event )

protectedvirtual

A simple "update-ahead" implementation that issues an update a little bigger to accommodate the possible following outline.

The point is that canvas rendering comes through two stages of compression and the canvas may request outline update when the outline itself has already been changed. It causes visual tearing on the screen (see https://bugs.kde.org/show_bug.cgi?id=476300).

We can solve that in two ways:

1) Pass the actual outline with the update rect itself, which is a bit complicated and may result in the outline being a bit delayed visually. We don't implement this method (yet).

2) Just pass the update rect a bit bigger than the actual outline to accommodate a possible change in the outline. We calculate this bigger rect by offsetting the rect by the previous cursor offset.

Don't try to update-ahead if the offset is bigger than 50% of the brush outline

10% of extra move is added to offset

Here is a weird heuristics on when to restore brush opacity and when not. Basically, we should restore opacity to its saved if the brush preset hasn't changed too much, that is, its version is the same and it hasn't been reset into a clean state since then. The latter condition is checked in a fuzzy manner by just mangling the isDirty state before and after.
