Craig Mautner 4bf18a7c97 Handle keyguard visibility states separately.
Previous to this change the forceHiding variable was a boolean. This
change recognizes the different configurations of the keyguard by
defining separate states for forceHiding and testing for window
visibility differently in each state.

Fixes bug 6786114.
