Florian Müllner 106d332c71 backend/xcursor: Support a "blank" cursor type 
We don't have enough Xlib code in mutter ...

Joking aside, it can be useful to make the cursor invisible
without hiding it, for example for replacing the actual cursor
with an actor in gnome-shell; the real cursor should still
update the focus surface in that case, and not sneak into
screenshots or -casts.
