For performance reasons, can createBackground be integrated into toCanvas? This would reduce one canvas conversion.

snapdom/src/exporters/download.js

Lines 29 to 31 in 4459231

const canvas = await toCanvas(url, options)
/* v8 ignore next */
const finalCanvas = options.backgroundColor ? createBackground(canvas, options.backgroundColor) : canvas
