Fix pixel noise in X11 systray icons that are not 22x22

Browse Source 
If a system tray icon is set to a non default size by an X11 system tray,
the area beyond 22x22 will not be painted, since the first paint is
performed before the first resize, and the first resize does not trigger
expose either.

The bug can be seen in KDE if the system tray is not 22 pixel height.
This patch triggers updates on resize to ensure we always repaint
fully on resize.
