Those number come from abstracting the object managment code from the
ObjectiveC runtime glib/gobject and a few java runtimes. Its about

Right now to much to be used outside of supporting gtk which is a pity
its a pretty good C object model.

No not a problem I understand how it works. I think there is a real
need for a companion text layout library for cairo It would be nice if
pango/gobject/glib could be thinned down to be that library since
pango has a lot of abilities.

If not then I'm sure over time some other library will be developed
that meets this need.
