by Sven GothelBug 1249: NEWT/X11 Visibility: Listening to more events for updated
state; Adding QUIRK_BIT_VISIBILITY
1) More visibility detection on post ConfigureNotify events, since the
latter may not yet contain the updated visibility state as it whould
(WM bug!):
- EnterNotify
- LeaveNotify
- Disabled
- Expose
- VisibilityNotify
2) Introducing quirks.
Setting QUIRK_BIT_VISIBILITY to handle the issue where
visibility -> false could not even be set.
