windowManager: Handle fullscreening from zero sized windows

Browse Source 
Wayland clients can request their surfaces to be fullscreened before
commiting a buffer which means that we need to handle fullscreen
requests for which the old size is 0x0, preferably without warnings.

Since the mapping animation also runs for these windows, we can simply
bail out and ignore the fullscreen size change.
