Struct GpuGlyph 

#[repr(C)]
pub struct GpuGlyph {
    pub bounds: [f32; 4],
    pub uv_bounds: [f32; 4],
    pub color: [f32; 4],
    pub clip_bounds: [f32; 4],
    pub clip_fade: [f32; 4],
    pub flags: [f32; 4],
}

A GPU text glyph instance (matches shader GlyphInstance struct)

Memory layout:

• bounds: vec4<f32> (16 bytes) - position and size
• uv_bounds: vec4<f32> (16 bytes) - UV coordinates in atlas
• color: vec4<f32> (16 bytes) - text color
• clip_bounds: vec4<f32> (16 bytes) - clip region (x, y, width, height)
• clip_fade: vec4<f32> (16 bytes) - overflow fade distances (top, right, bottom, left) Total: 96 bytes

Fields

bounds: [f32; 4]

Position and size (x, y, width, height)

uv_bounds: [f32; 4]

UV coordinates in atlas (u_min, v_min, u_max, v_max)

color: [f32; 4]

Text color (RGBA)

clip_bounds: [f32; 4]

Clip bounds (x, y, width, height) - set to large values for no clip

clip_fade: [f32; 4]

Overflow fade distances (top, right, bottom, left) in pixels

flags: [f32; 4]

Flags: [is_color, unused, unused, unused] is_color: 1.0 for color emoji (use color atlas), 0.0 for grayscale (use main atlas)
