- * a color (case insensitive match) or a 0xRRGGBB[AA] sequence,
- * possibly followed by "@" and a string representing the alpha
- * component.
- * The alpha component may be a string composed by "0x" followed by an
- * hexadecimal number or a base-10 number between 0 and 255, or a
- * decimal number between 0.0 and 1.0, which represents the opacity
- * value (0/0x00/0.0 means completely transparent, 255/0xff/1.0
- * completely opaque).
- * If the alpha component is not specified then 255 is assumed.
- * The string "random" will result in a random color.
- * @return >= 0 in case of success, a negative value in case of
- * failure (for example if color_string cannot be parsed).
