[svgwg] CSS Gradients (#1021)

Tavmjong has just created a new issue for https://github.com/w3c/svgwg:

== CSS Gradients ==

CSS gradients, defined in CSS Images Module [Level 3](https://www.w3.org/TR/css-images-3/) and [Level 4](https://www.w3.org/TR/css-images-4/), offer several things missing in SVG gradients:

- Defining gradients in CSS rather than elements.
- Conical gradients.
- Interpolation in different color spaces.

Of these features, the most interesting from our (Inkscape) perspective, is being able to define the color space for interpolation. Interpolation in polar color-spaces, in general, produces much better looking gradients that interpolation in sRGB or linear-RGB, avoiding the gray-washout typical found in the center of a gradient.

There are several options for updating SVG gradients:

1. Reference CSS Images Module 4. In this case, one needs to define the SVG equivalent of the _**[gradient box](https://www.w3.org/TR/css-images-4/#gradient-box)**_.
2. Reference parts of CSS Images Module 4 (probably not useful).
3. Directly update SVG's gradients. In particular, add additional values to the property _[color-interpolation](https://www.w3.org/TR/SVG2/painting.html#ColorInterpolation)_.
4. Do nothing.
