Well variables returned from layout *are* pretty important :^)
As for parent-face I don't know if that is really a problem, just a matter
of usage, we know it it gets calculated after View been activated.

Ah that example helps considerably :^)
Yes it does look like a problem.

Now doubt you'll see my later message - which I think fixes this problem.

Thanks for your patches, I'm going to add them to my patches.r script along
with my change to layout.
