Type Alias GlyphPresenceTest

GlyphPresenceTest: (glyph: string, font: IconStyleFont) => boolean

Whether a font has a glyph, decided by measuring it.

Implemented by the caller so this module stays free of canvas and testable without one. Returns true when glyph renders from font rather than falling back.
