The CanvasGradient interface represents an opaque object describing a gradient. It is returned by the methods CanvasRenderingContext2D.createLinearGradient(), CanvasRenderingContext2D.createConicGradient() or CanvasRenderingContext2D.createRadialGradient().
It can be used as a fillStyle or strokeStyle.
As an opaque object, there is no exposed property.
CanvasGradient.addColorStop()
Adds a new stop, defined by an offset and a color, to the gradient.
