- * @param color_string a string specifying a color. It can be the name of
- * a color (case insensitive match) or a [0x|#]RRGGBB[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 decimal number between 0.0 and 1.0, which
- * represents the opacity value (0x00/0.0 means completely transparent,
- * 0xff/1.0 completely opaque).
- * If the alpha component is not specified then 0xff is assumed.
- * The string "random" will result in a random color.
- * @param slen length of the initial part of color_string containing the
- * color. It can be set to -1 if color_string is a null terminated string
- * containing nothing else than the color.
- * @return >= 0 in case of success, a negative value in case of
- * failure (for example if color_string cannot be parsed).
