jean-pierre charras 15cc368918 Gerber plotter: prepare optimization of aperture macros type free polygons. 
They are used for chamfered round rect pads, and can be used for custom shaped pads.
No actual change currently, but the shape rotation of custom pads and chamfered rr pads
can be now used in gerber plots.
