 * pidgin_color_calculate_for_text:
 * @text: The text to calculate a color for.
 * @color: (out): The return address for a #GdkRGBA that will receive the
 *         color.
 *
 * This function is based heavily on the implementation that gajim uses from
 * python-nbxmpp in nbxmpp.util.text_to_color.  However, we don't have an
 * implementation of HSL let alone HSLuv, so we're using HSV which is why
 * the value is 1.0 instead of a luminance of 0.5.
 *
 * Currently there is no caching as GCache is deprecated and writing a fast LRU
 * in glib is going to take a bit of finesse.  Also we'll need to figure out how
 * to scale to ginormous Twitch channels which will constantly bust the cache.
 *
 * Since: 3.0.0
