Bug 1239864 (part 1) - Add new, nicer rect-iterators for nsRegion and nsIntRegion. r=roc. This requires renaming the existing nsIntRegion::RectIterator as nsIntRegion::OldRectIterator to make way for the new nsIntRegion::RectIterator. This doesn't require many knock-on changes because most existing uses of that type use the nsIntRegionRectIterator typedef.
