I olden days, the Quickdraw Toolbox had something called 'graphics mode' (I think) which applied a boolean expression to graphics drawing objects. I think 'XOR' was the default mode, and 'OR' mode (if I recall correctly) does exactly what you describe... flips whatever is being drawn over a black background to white. There were (are?) 8 modes to choose from. I don't know whether this has been deprecated, or not. If not, perhaps this can still be invoked via Declares. You should probably search the Apple tech resources.
