Feature request: possibility of baking in line height

[ajitid]

Use-case: If you customize fonts like Input you'd find that they let you bake in line height as well. This is useful in the cases where modifying line height in an app has an odd effect (eg. in Kitty app, line height produces unintended spacing at the top and bottom of the terminal) or modifying line height properly isn't possible (eg. Emacs). It'd be great if Fontfreeze lets you bake that in as well.

I might need some help on this. I've tried various ways of playing around with sTypoAscender etc. without getting the desired effect. In some combinations, where the line gap does change, the relative font size also changes (which is not desirable).
