 * Rasterizes at `pixelRatio` to keep the texture sharp on HiDPI / 4K displays.
 * `width`/`height` are interpreted as the logical (CSS-pixel) target size; the
 * backing canvas is allocated at `width * pixelRatio` × `height * pixelRatio`.
 *
 * When `sw`/`sh` are provided they describe a source-region crop on the SVG
 * (not a crop of the destination canvas) and are sampled via the 9-arg form of
 * drawImage.
 *
 * Returns an `ImageBitmap` when available (zero CPU readback, transferable),
 * falling back to `ImageData` on older browsers without `createImageBitmap`.
