Required Methods

fn font_size(&self, line: usize) -> usize

Get the ‘general’ font size for a specific buffer line.

This is typically the editor font size.

There might be alternate font-sizes within the line, like for phantom text, but those are not considered here.

fn cache_id(&self) -> FontSizeCacheId

An identifier used to mark when the font size info has changed.

This lets us update information.
