cluttermm: Branch before wrapping 0.7/0.8 API?

[Armin Burgmeier <armin arbur net>]

I intent to wrap new clutter API in cluttermm. The 0.7 version of
clutter is not API stable with 0.6, though, meaning we need to change
cluttermm API as well. Should I do this in another branch, or should I
branch the current trunk before, or can this go into trunk without
branching?

Thanks,
Armin
