Subject: [PATCH] quartz: delay emission of EnterNotify until window position
 is known

Beforehand, the check whether or not emission is necessary was done
based on the "uninitialized" window position in the top left corner.
We now wait until the window size is set for the first time, to avoid
emitting EnterNotify when it is not necessary.
