commit 8745da6d591a1f18f21eb12651265d14be730d6e
Author: Sebastian Geiger <sbastig gmx net>

multiscreen: remove GdkScreen
Since there is only one GdkScreen object it is not
necessary to pass the 'screen' pointer around
between functions.
Also the global 'screens' variable is obsolete
since it can only ever contain a single screen
object.
