EternalLands - that's what I was planning on doing anyway, I just didn't see any primitive operators with which to do it. What I don't want to do if I don't have to is reinvent the rectangle drawing primitive from scratch, just to do this.

Richard â thanks, that sounds like a good plan. So I think you're telling me that setting up the OpenGL LogicOp will modify ALL drawing done through the window, SDL primitives as well as OpenGL primitives. Right? (And is there any significant downside to specifying "opengl" as my driver, instead of the usual default?)

Thanks,
Ken
