+ * When possible, converts color specified as a full range value in
+ * the fromFormat, into an equivalent full range color in the toFormat.
+ * When conversion is impossible (e.g. out of gamut color) a color
+ * or black in the full range output format is produced. The input
+ * color is given as a fractional color in the parameter named color.
+ * The produced color is written over the same parameter used to
+ * provide the input color.
+ *
+ * Each graphic format has 3 color components and each of these
+ * components has both a full and in gamut range. This function uses
+ * a table that provides the full and in gamut ranges of each of the
+ * supported graphic formats. The full range is given by members named
+ * c[123]Min to c[123]Max, while the in gamut range is given by members
+ * named c[123]Low to c[123]High. In most cases the full and in gamut
+ * ranges are equivalent. This occurs when the c[123]Min == c[123]Low and
+ * c[123]High == c[123]Max.
+ *
+ * The input and produced colors are both specified as a fractional amount
+ * of the full range. The diagram below provides an overview of the
+ * conversion process. The main steps are:
+ *
+ * 1. Produce black if the input color is out of gamut.
+ *
+ * 2. Convert the in gamut color into the fraction of the fromFromat
+ * in gamut range.
+ *
+ * 3. Convert from the fraction of the in gamut from format range to
+ * the fraction of the in gamut to format range. Produce black
+ * if an equivalent color does not exists.
+ *
+ * 4. Covert from the fraction of the in gamut to format to the
+ * fraction of the full range to format.
