Struct FallbackFace 

pub struct FallbackFace {
    pub font_id: FontId,
    pub family_name: String,
    pub postscript_name: String,
    pub units_per_em: u16,
    pub is_color_emoji: bool,
}

Fallback font identity metadata retained from a native system platform pass.

Plan §13.7: “A native glyph ID has meaning only with the actual fallback font/run that produced it. The native adapter retains or converts that font identity…”

family_name: String

postscript_name: String

PostScript name of the font face.

units_per_em: u16

Font design units per em.
