+   II)
+
+   The design of scrolling in wxWidgets is markedly different from that offered
+   by the GTK itself and therefore we cannot simply take it as it is. In GTK,
+   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 sub-windows. 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.
+
+   III)
+
+   Singularly the most broken code in GTK is the code that is supposed to
+   inform subwindows (child windows) about new positions. Very often, duplicate
+   events are sent without changes in size or position, equally often no
+   events are sent at all (All this is due to a bug in the GtkContainer code
+   which got fixed in GTK 1.2.6). For that reason, wxGTK completely ignores
+   GTK's own system and it simply waits for size events for toplevel windows
+   and then iterates down the respective size events to all window. This has
+   the disadvantage that windows might get size events before the GTK widget
+   actually has the reported size. This doesn't normally pose any problem, but
+   the OpenGL drawing routines rely on correct behaviour. Therefore, I have
+   added the m_nativeSizeEvents flag, which is true only for the OpenGL canvas,
+   i.e. the wxGLCanvas will emit a size event, when (and not before) the X11
+   window that is used for OpenGL output really has that size (as reported by
+   GTK).
+
+   IV)
+
+   If someone at some point of time feels the immense desire to have a look at,
+   change or attempt to optimise the Refresh() logic, this person will need an
+   intimate understanding of what "draw" and "expose" events are and what
+   they are used for, in particular when used in connection with GTK's
+   own windowless widgets. Beware.
+
+   V)
+
+   Cursors, too, have been a constant source of pleasure. The main difficulty
+   is that a GdkWindow inherits a cursor if the programmer sets a new cursor
+   for the parent. To prevent this from doing too much harm, I use idle time
+   to set the cursor over and over again, starting from the toplevel windows
+   and ending with the youngest generation (speaking of parent and child windows).
+   Also don't forget that cursors (like much else) are connected to GdkWindows,
+   not GtkWidgets and that the "window" field of a GtkWidget might very well
+   point to the GdkWindow of the parent widget (-> "window-less widget") and
+   that the two obviously have very different meanings.
