Font upscaling / new font discussion

For me it's always kind of hard to tell from pictures instead of the real watch, but I think it looks good in the menu bar.
To me it looks just too small/large in the scroller, but we could maybe resize scroll items?

say: "I want a bitmap font 20px high" and let Espruino choose?

This would be nice to have. (And people could customize fonts globally without messing up layouts.)
