+   for the parent. To prevent this from doing too much harm, SetCursor calls
+   GTKUpdateCursor, which will recursively re-set the cursors of all 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.
