I modified the osgwidgetcanvas example.
- a compositeviewer with two views
- each view has a window/canvas object
- put one window in foreground (the other should be maximized/bigger in
background)
- try to resize the first window
-> both windows get the resize event
- if you don't see the bug, change focus, minimize/maximize again
