Allan Sandfeld Jensen cc3875c2e4 Balloon tip must follow systemtray icon
If the a message notification is created at the same time as the system
tray icon is embedded it may start at a wrong location, since the icon
location it bases its own location is not yet final.

This patch adds code to update the balloon tip location when the system
tray icon is moved or resized.

The bug and fix can be tested by the systray example by disabling the
icon and letting show message trigger both showing it and the message.
