Struct GlyphInstance 

#[repr(C)]
pub struct GlyphInstance {
    pub position: [f32; 3],
    pub scale: [f32; 2],
    pub rotation: f32,
    pub color: [f32; 4],

}

Per-instance GPU data. Must match the vertex shader layout exactly.

Layout (84 bytes total, 21 × f32): position : vec3 (offset 0) scale : vec2 (offset 12) rotation : f32 (offset 20) color : vec4 (offset 24) emission : f32 (offset 40) glow_color : vec3 (offset 44) glow_radius: f32 (offset 56) uv_offset : vec2 (offset 60) uv_size : vec2 (offset 68) _pad : vec2 (offset 76) — aligns to 84 bytes
