  If you don't plan to use Cairo with gtk+, nothing important.  If you
want to use cairo, there's at least gdk_drawable_create_cairo_context
which can be considered crucial.  And the whole pango-cairo library
also, if you need to draw text with Cairo.

  According to the GNOME 2.12 release schedule[1], API freeze is
happening right about now.  The only question remaining is whether GNOME
2.12 will use GTK+ 2.8 or GTK+ 2.6, if I understood correctly.  [ A
shame really if we have to stick to GTK+ 2.6 for 6 more months, if you
ask me... ]

  What does "we" refer to here?  C++ bindings?  There are already
reasonably stable (but complete) Cairo bindings for python, and PyGTK
2.7 optionally depends on them.
