Select font_face by font name string

[dansimco]

This is something I'm interested in implementing, opening an issue here to discuss feasibility and potential pitfalls.

Assuming this is a desirable feature, would it be preferable to add a check if the input to screen.font_face(i) is number or a string, or would it be best a separate function. Separate function seems noisier but I'm wondering if doing a string check inside redraw loop is wasted cycles.

this is an incredibly reasonable proposition!

can be the same function and check arg type.

ah, just sunk in that it'd be called a lot in the redraw. there's likely an optimized approach, let's think on it.

I don't love this idea, but there's potentially a get_font_index(str) angle here to do the lookup manually.

i'm wondering if passing the string to the C layer is faster than just having a lookup table within lua

That might be enough? Thinking about this for a couple of days, of all the logic I've shoved into the redraw loop, these checks would not be the biggest offender by a long shot.

edit: How might we measure the impact of a particular approach?
