@gmbecker should propose_column_widths get different results for different font sizes? It does not change any font size I input

[gmbecker]

this is down to the grid system, I think. the font information is all set at the same time, and it seems to ignore size if it doesn't understand the font family. I'll look into whether this is intented behavior or not, but if it is there won't be much we can (or, arguably, should) do about it
