31 * Put the RGBA values that correspond to color_string in rgba_color.
33 * @param color_string a string specifying a color. It can be the name of
34 * a color (case insensitive match) or a 0xRRGGBB[AA] sequence,
35 * possibly followed by "@" and a string representing the alpha
37 * The alpha component may be a string composed by "0x" followed by an
38 * hexadecimal number or a base-10 number between 0 and 255, or a
39 * decimal number between 0.0 and 1.0, which represents the opacity
40 * value (0/0x00/0.0 means completely transparent, 255/0xff/1.0
42 * If the alpha component is not specified then 255 is assumed.
43 * The string "random" will result in a random color.
44 * @return >= 0 in case of success, a negative value in case of
45 * failure (for example if color_string cannot be parsed).
