  42:  * ColorSpaceConverter - used by java.awt.color.ICC_ColorSpace
  43:  *
  44:  * Color space conversion can occur in several ways:
  45:  *
  46:  * -Directly (for the built in spaces sRGB, linear RGB, gray, CIE XYZ and PYCC
  47:  * -ICC_ProfileRGB works through TRC curves and a matrix
  48:  * -ICC_ProfileGray works through a single TRC
  49:  * -Everything else is done through Color lookup tables.
  50:  *
  51:  * The different conversion methods are implemented through
  52:  * an interface. The built-in colorspaces are implemented directly
  53:  * with the relevant conversion equations.
  54:  *
  55:  * In this way, we hopefully will always use the fastest and most
  56:  * accurate method available.
