Bad example.  You should have mentioned MS-DOS where every application
is very bad because the programmer spends ages on writing display and
printer drivers instead of writing a Good Program.

Window refreshing must be done by the task owning the window.  It must
get information on the region of the screen to be update from the
window manager.  Having the window manager store bitmaps is stupid,
restricting and it consumes much too much memory.
