I think the recommended route is to make a window that fills the screen, rather than taking the entire screen as a GrafPort. If you want the code to be portable, you can make your fullscreen window, draw to an offscreen GWorld, and CopyBits to the window. There’s a whole song and dance that you do in order to make sure that this is fast.

Later on, there was DrawSprocket. It solved the problem of figuring out how to do “portable” and “fast” at the same time, and let you use features like page flipping, if the hardware supported it (saving you the call to CopyBits).
