This type defines a gradient between 2 symbolic colors, with any number of color stop between these. At the moment it has been put besides GtkSymbolicColor, although should be completely private, it will likely need extending in the future for radial gradients. At some point, it maybe should also be used for images, so painting both a gradient and an image is consistent.
