I still see some limitations in GimpGradient, and in particular, they are still always stored as RGB in GGR files. It would be nice if we could store the actual color format. This way, if someone chooses a gradient stop as Lab or CMYK color, that's what the gradient file would keep track of. But also even storing the space of a color (instead of storing/loading always in sRGB, even though this may still work fine as we store unbounded double values). This might warrant for a v2 of GGR file format. This commit also fixes loading of SVG gradient which was apparently broken regarding hexadecimal color parsing. Finally I improve gegl_color_set_alpha() by adding an alpha channel when the initial format had none.
