See discussion originally posted by @HenningTm in #3224.

Setting save_final_image property of jsPsychSketchpad plugin to true, which invokes the toDataURL method of a canvas, causes Tainted canvases may not be exported error. This might be fixed by adding this.background_image.crossOrigin = 'Anonymous'; during image loading.
