LibVT: Relayout TerminalWidget on font change

Browse source 
We were not recomputing the internal dimensions after a font changed,
which caused things to look very off.

It's still not perfect as we're always using the same (small) font for
bold text, which obviously sticks out like a sore pinky when the rest
of the terminal text is large.
