memorizes how much it has been scrolled but that wxWindows forgets this
so that the two coordinates systems have to be kept in synch. This is done
in various places using the pizza->xoffset and pizza->yoffset values.

Singularily the most broken code in GTK is the code that is supposes to
inform subwindows (child windows) about new positions. Very often, duplicate
events are sent without changes in size or position, equally often no

intimate understanding of what a "draw" and what an "expose" events are and
what there are used for, in particular when used in connection with GTK's
own windowless widgets. Beware.
