Struct GlyphQuad 

pub struct GlyphQuad {
    pub key: u64,
    pub bitmap: CachedGlyph,
    pub x: f32,
    pub y: f32,
    pub w: u32,
    pub h: u32,
    pub color: [u8; 4],
}

One glyph headed for the compositor’s atlas (D109 Step 4): position and color per frame; bitmap is the shared cached rasterization, read only on the atlas’s first sight of key.

Fields

key: u64

Stable atlas key (see font::layout_glyphs).

bitmap: CachedGlyph

Coverage bitmap (w*h bytes) — pre-gamma; the atlas upload applies the text gamma curve once (see text_gamma_lut).

x: f32

Top-left, physical px.

y: f32

w: u32

h: u32

color: [u8; 4]

sRGB straight-alpha text color.
