The purpose of the methods to transform to/from the well-defined CIEXYZ color space is to support conversions between any two color spaces at a reasonably high degree of accuracy. It is expected that particular implementations of subclasses of ColorSpace (e.g. ICC_ColorSpace) will support high performance conversion based on underlying platform color management systems.

The CS_CIEXYZ space used by the toCIEXYZ/fromCIEXYZ methods can be described as follows:

       CIEXYZ       viewing illuminance: 200 lux       viewing white point: CIE D50       media white point: "that of a perfectly reflecting diffuser" -- D50       media black point: 0 lux or 0 Reflectance       flare: 1 percent       surround: 20percent of the media white point       media description: reflection print (i.e., RLAB, Hunt viewing media)       note: For developers creating an ICC profile for this conversion             space, the following is applicable.  Use a simple Von Kries             white point adaptation folded into the 3X3 matrix parameters             and fold the flare and surround effects into the three             one-dimensional lookup tables (assuming one uses the minimal             model for monitors).
