*
* GeglColor accepts a subset of format string as defined by the CSS color specification:
* http://dev.w3.org/csswg/css-color/
*
* - RGB hexadecimal notation: #rrggbb[aa] / #rgb[a]
* - Named colors, limited to the 16 specified in HTML4
*
* To specify linear-light floating-point RGB, use: rgb[a](0.40, 0.44, 0.92 [, a])
* The normal bounds are [0.0 1.0], unlike CSS which is [0 255]. Out-of-bounds values are allowed.
