	ScaleFX is an edge interpolation algorithm specialized in pixel art. It was
	originally intended as an improvement upon Scale3x but became a new filter in
	its own right.
	ScaleFX interpolates edges up to level 6 and makes smooth transitions between
	different slopes. The filtered picture will only consist of colours present
	in the original.
