Seems like we it would be elegant to add an overload of colorWithOverrideAlpha that takes an Optional. It can be inlined, but it would be nice to have it there, rather than writing it out here.

I think just "= 1" would be nicer.

Ditto.

> Source/WebCore/html/canvas/CanvasRenderingContext2D.idl:166
> +        optional unrestricted float alpha = 1.0);

Ditto.
