/**
 * ColorSpaceConverter - used by java.awt.color.ICC_ColorSpace
 *
 * Color space conversion can occur in several ways:
 *
 * -Directly (for the built in spaces sRGB, linear RGB, gray, CIE XYZ and PYCC
 * -ICC_ProfileRGB works through TRC curves and a matrix
 * -ICC_ProfileGray works through a single TRC
 * -Everything else is done through Color lookup tables.
 *
 * The different conversion methods are implemented through
 * an interface. The built-in colorspaces are implemented directly
 * with the relevant conversion equations.
 *
 * In this way, we hopefully will always use the fastest and most
 * accurate method available.
