Struct AnimQuadVertex 

#[repr(C)]
pub struct AnimQuadVertex {
    pub position: [f32; 2],
    pub uv: [f32; 2],
    pub slot: u32,
    pub _pad: u32,
}

Vertex for the shader-driven animated-quad pipeline (procedural and sprite kinds). All four vertices of a quad carry the same slot, which the fragment shader uses to look up per-frame state (phase, resolved colors, atlas dims) in the anim_uniforms buffer. No color or timing is baked in the vertex — that’s the whole point: rebuilding the vertex batch is unnecessary when only the phase changes, so the widget’s paint() doesn’t re-run per frame.

Fields

position: [f32; 2]

Pixel position; converted to NDC in the render loop.

uv: [f32; 2]

Local UV within the quad (0..1 across each axis). The fragment shader uses uv.x to decide sweep inclusion; the sprite shader combines it with AnimParams::atlas_cols/atlas_rows to sample the atlas cell.

slot: u32

Index into the renderer’s AnimParams uniform array. Same for all four vertices of a quad; declared @interpolate(flat) in WGSL to preserve the integer across rasterization.

_pad: u32

Struct padding to keep stride a multiple of 8 bytes (matches QuadVertex convention for wgpu vertex-buffer layouts).
