Marcel Kilgus makes some magical things to make me read } } What? That 32bit per pixel is far too memory consuming for a windowing } system that does the saving of backgrounds itself? Nothing proprietary } in this knowledge ;-) } } The PE was designed for 2 bit per pixel with a small resolution and } the concept was good for that purpose. It's however a very bad design } if you have more bits per pixel (one single(!) 800x600 window almost } needs 2MB in 32 bit mode!).
It would be better if PE was able to compress the saved area on the fly, or even better, perform no saving and require a (re-)drawing routine from each application. But then this would be trading memory for CPU and more problems for the applications.
