restoring a minimized window on Windows CE didn't work

After restoring a minimized window we only saw the window decoration.
All content was missing. That's because we don't get a WM_SIZE message
for restoring the window. We must react on WM_ACTIVATE in this case.
This fixes the issue for Windows mobile too.
