Normally one might expect, that one wxWidgets window would always correspond

the functionality. Moreover, the GTK defines a client area as a different
widget from the actual widget you are handling. Last but not least some
special classes (e.g. wxFrame) handle different categories of widgets and
clicking on a scrollbar belonging to scrolled window will inevitably move
the window. In wxWidgets, the scrollbar will only emit an event, send this
to (normally) a wxScrolledWindow and that class will call ScrollWindow()
- which actually moves the window and its subchildren. Note that GtkPizza

memorizes how much it has been scrolled but that wxWidgets 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.
