LGTM

It's hard to believe this bug is in there, but if we have to deal with it this
looks like a reasonable way.

This was bugging me a bit, so I stepped into Pango to figure out what
is going on. It looks like Pango uses the size of whitespace when
calculating were to break, but that whitespace isn't reported when you
ask for the size. This means to correctly determine the wrapped size
we have to include whitespace. As that can be a bit of headache
(multiple space characters, and the size of a tab), I'm sticking with
my current patch.

I wonder if it's the difference between the ink rect and the logical rect?

I tried and that isn't it. I believe it's as I said, the size of
whitespace is used when breaking, but is not reported in the logical
rect.
