[whatwg] Addition of a setExtend(in DOMString extend) method to the CanvasGradient interface

[Jonathan Watt]

The extend mode of canvas gradients isn't under user control as it is in SVG.
I'd like to propose adding a setExtend(in DOMString extend) method to the
CanvasGradient interface[1], where the method would accept the arguments "none",
"repeat", "reflect" and "pad". These would be defined similarly to the values
that the 'spreadMethod' attribute on SVG gradients accepts[2].
