Binary compatability

[Marius Vollmer <mvo zagadka ping de>]

Yo,

what's the current word on binary backwards compatability in Gtk?

I have been away from the sources for a long time now and I want to
work my way back in.  The first thing I have in mind is to clean up
the object/type system and in the process make it fit for defining new
Gtk classes from Scheme and other dynamic languages.

I have no specific things in mind right now but I'd like to know if
breaking binary compatability is a problem.  I think I can keep source
compatability no matter what.
