1//! Backend-neutral glyph placement produced by the text layout pipeline.
2
3/// One positioned glyph in logical layout space.
4///
5/// The matching font bytes remain owned by [`crate::TextSystem`]. Coordinates
6/// are logical pixels relative to the layout origin; they are not rounded to
7/// device pixels. `color` is absent for layouts that use one caller-supplied
8/// paint color and present for styled runs that carry their own color.
9///
10/// # Examples
11///
12/// ```
13/// use ailloli_ui_text::GlyphInstance;
14///
15/// let glyph = GlyphInstance {
16///     face_id: 7,
17///     font_index: 0,
18///     glyph_id: 42,
19///     px_size: 16,
20///     x: 12.5,
21///     y: 20.0,
22///     color: None,
23/// };
24/// assert_eq!(glyph.glyph_id, 42);
25/// assert_eq!(glyph.color, None);
26/// ```
