Hi Mike, have a look here: http://bazaar.launchpad.net/~kicad-testing-committers/kicad/kicad-gal/view/head:/gal/common/graphics_abstraction_layer.h
This is the base class. As application developer you have to know only this class and its methods. The implementation is the job of the GAL implementer; currently I've implemented OpenGL (hardware acceleration) and cairo (software renderer). So both share the same interface. I've also an experimental wxDC implementation; just for evaluation and performance comparision (not yet checked in). I've tried to make the interface relative simple .. hope that will be a success.
