Functions
template<class Visitor >
bool	processActiveEdges (ActiveEdgeCuts &activeEdges, const Rect2i &region, Visitor &visitor)
	Process all active edges at current y, advance y, remove any edges that are finished, then return. More...
template<class Visitor >
bool	processTwoActiveEdges (ActiveEdgeCuts &activeEdges, const Rect2i &region, Visitor &visitor, const int nextY)
	Optimization of processActiveEdges() for exactly 2 active edges: None of them can finish before another edge gets active (or the polygon is done) - designated by nextY. More...
template<class Visitor >
bool	processIntervals (const ActiveEdgeCuts &activeEdges, Intervals &intervals, const Rect2i &region, Visitor &visitor, uint precision)
template<class Visitor >
bool	processActiveEdges (ActiveEdgeCuts &activeEdges, Intervals &intervals, const Rect2i &region, Visitor &visitor, uint precision)
	See above. More...
