Function descent 

pub fn descent(font: Font, size: f32) -> f32

Descender depth for font at size points, as a positive number (the AFM/TTF storage convention is negative; both backends normalise on the way out).

Examples

use mos_fonts::{Base14Font, Font, descent};

assert!(descent(Font::Base14(Base14Font::Helvetica), 10.0) > 0.0);
