GTK+ finally has been branched for the next release cycle, which means
that features can be added. So it seems to be a good time to descibe the
extended layout patches I've created during this Summer of Code:

Ok, right. But

Hi,
While I haven't looked at the patches in detail, based on your writeup
it feels like the interfaces here will make it a little hard to
implement in widgets.
In HippoCanvas I ended up with this:

I am not convinced this is always the best strategy. Doesn't this

I think you misunderstand the intent; you said "here's the proposal" and
I asked some questions and said "what about doing it this way"
You are very welcome to
