I have an experiment I'm working on that requires me to "fool" the Mac into redirecting all of it's graphics into an off-screen bitmap. By all graphics, I mean everything, Menu bar, all windows, mouse pointer...etc. Since this is just an experiment the method doesn't have to be able to work for everything, as long as I can run some word processing and drawing programs with it turned on. I should mention that I need a method that works with color quickdraw on a Mac II. I would be particularly interested in a method that would allow the offscreen bitmap to be bigger than the standard Mac screen. Also, if there was a way to trick the Mac into scaling up the fonts and menubars so they came out bigger on the bigger screen it would be helpful. (ie: if the offscreen bitmap was twice the size of a normal Mac screen it would cause 24 point fonts to be used instead of 12 point ones and the menu bar would be twice as tall.) The application is some visual preception experiments, the offscreen bitmap will be processed slightly and copied back to the "real" screen at regular intervals as fast as possible.
