I have been working on different features in separate repositories,
and sometimes my checkins are not in sync.   I was also building
with C++, which is rather more forgiving.  I've checked you patches
where I hadn't already fixed the problem.

I'm a newbie to Gtk, so I don't know anything about why Gtk would
want to use RANDR.  The only answer I can give is to add the
Xrender extension.   It's enough work to get anything working at all. :-)
