Interface PatternPaint

A §58 pattern: a texture sampled over the shape's own uv — the [0, 1]² parameterization of its bounding box that every shape geometry already carries — covering two of §58's rows at once, because the texture seam is MaterialTexture: an image pattern binds a Texture, and a render-target texture binds a RenderTarget.colorTexture, with no adapter between them (R-4's seam, exactly as NodeMaterial.setTexture documents it).

const tiles: PatternPaint = {
  kind: "pattern",
  texture: bricks,                 // or offscreenTarget.colorTexture
  repeat: { x: 4, y: 2 },          // uv is multiplied, then offset
};
Copy

Tiling past [0, 1] is the texture's own wrap mode's business (§77) — the paint transforms the coordinate and the sampler decides what lies beyond, so repeat: { x: 4 } tiles a "repeat" texture four times and clamps a "clamp" one, both honestly.
