Yes, given that libcairo-gobject is a separate library shipped with 
libcairo, I think it would make sense to add a Cairo::GObject module to 
the Cairo distribution.

I actually set out to do just that, but I immediately hit a very 
familiar brick wall: thread safety.  You see, cairooverlay emits its 
various signals (including "draw"), from a non-main thread.  The Perl 
bindings (specifically, Glib) cannot deal with this currently.  I tried 
resolving this issues multiple times in the past few years but haven't 
been able to come up with a solution.  I'll try to have another go at it 
soon.  But if anyone else wants to chip in, let me know, I'll happily 
explain all the details.
