Subject: [PATCH] x0vncserver: update/display cursor only on correct screen in
zaphod mode
We have to check whether we update cursor position/shape only in case
the cursor is on our display, otherwise in zaphod mode, ie. when having
two instances of x0vncserver on screens :0.0 and :0.1 we would be having
the cursor duplicated and actually not funcional (aka ghost cursor) as
it would be actually not present. We also additionally watch EnterNotify
and LeaveNotify events in order to show/hide cursor accordingly.
Change made with help from Olivier Fourdan <ofourdan@redhat.com>
