/**
* This abstract class is used to serve as a color space tag to identify the
* specific color space of a Color object or, via a ColorModel object,
* of an Image, a BufferedImage, or a GraphicsDevice. It contains
* methods that transform colors in a specific color space to/from sRGB
* and to/from a well-defined CIEXYZ color space.
* <p>
* For purposes of the methods in this class, colors are represented as
* arrays of color components represented as floats in a normalized range
* defined by each ColorSpace. For many ColorSpaces (e.g. sRGB), this
* range is 0.0 to 1.0. However, some ColorSpaces have components whose
* values have a different range. Methods are provided to inquire per
* component minimum and maximum normalized values.
* <p>
* Several variables are defined for purposes of referring to color
* space types (e.g. TYPE_RGB, TYPE_XYZ, etc.) and to refer to specific
* color spaces (e.g. CS_sRGB and CS_CIEXYZ).
* sRGB is a proposed standard RGB color space. For more information,
* see <A href="http://www.w3.org/pub/WWW/Graphics/Color/sRGB.html">
* http://www.w3.org/pub/WWW/Graphics/Color/sRGB.html
* </A>.
* <p>
* 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.
* <p>
* The CS_CIEXYZ space used by the toCIEXYZ/fromCIEXYZ methods can be
* described as follows:
<pre>
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).
</pre>
