Mike Williams 30987cebfe Gerbview: fix cairo negative items and implement real differential mode ... Layers with negative objects need to be drawn in a subsurface before copying so they don't _CLEAR the draw items below them when a negative object is drawn. Differential layers are basically the same thing only they use a different copying operation onto the layers below.
