}

Unified instance data shared by all three render tiers.

96 bytes total, 16-byte aligned. Encodes quads, text glyphs, and images as textured/untextured quads differentiated by draw_type.

Fields

position: [f32; 2]

Screen-space position (top-left corner).

size: [f32; 2]

Quad size in pixels.

uv_min: [f32; 2]

Texture UV min (0,0 for solid quads).

uv_max: [f32; 2]

Texture UV max (0,0 for solid quads).

color: [f32; 4]

Fill/tint/text color (RGBA, premultiplied alpha).

border_radius: f32

SDF corner radius in pixels.

border_thickness: f32

Border outline thickness (0 = filled).

texture_index: u32

Index into the texture array (0 for text atlas, 1..N for images).

draw_type: u32

Draw type discriminant: 0=quad, 1=text, 2=image.

clip_min: [f32; 2]

Shader-based clip rect min (screen space).

clip_max: [f32; 2]

Shader-based clip rect max (screen space).

z_depth: f32

Normalized depth (0.0=far, 1.0=near). Higher z_index maps to higher z_depth.

_reserved: [f32; 3]

Reserved for future use (rotation, flags, custom_data).
