	I'm working on an openGL graphics application. I want to know if drawing with a "XOR mode" (like in QuickDraw) is possible in openGL. If it is possible, I can display a selected object just drawing (using this XOR mode) a rectangle (o some other shape) over the object and than redraw the shape when deselecting the object, without need to redraw the entire scene. Any suggestions? (Sorry for my buggy english)
