-     * But it can be useful if :
-     * - IE < 11 (doesn't support msDisableImageSmoothing)
-     * - need to display a gap between pixel
-     *
-     * @param  {Canvas2d} source original image to be resized, as a 2d canvas
-     * @param  {Number} zoom   ratio between desired dim / source dim
-     * @param  {Number} margin gap to be displayed between pixels
-     * @param  {String} color or the margin (will be transparent if not provided)
-     * @return {Canvas2d} the resized canvas
