magnifier: Update screen position on activation

Browse Source 
The default ZoomRegion is created at startup and only updated if it is active
when the monitor setup changes. Thus when reactivating the magnifier after a
display change, the viewport used is still the one that been computed with the
old screen geometry values.

Move screen update code inside a function and call it both when activating
the zoom region and when the monitor changes during a zoom session.
