Every fill and stroke allocated a coverage mask the size of the whole canvas and painted every canvas pixel, so a vector file cost shapes × canvas area: SceneYard "Retro Desktop Movie Popups" spent 556 s per frame on one 4001×2501 Illustrator layer (568 s a frame in all). Each shape now rasterises and paints only inside its device-space bounding box (+1 px of anti-aliasing) clipped to the canvas; a stroke uses the bounds of its outline. The frame renders in 5–7 s (bench, no cache). Pixels match the whole-canvas version except a few anti-aliased edge pixels (float rounding of the re-based transform). A test checks that every pixel a shape covers lies inside its rectangle, and pins the output.
