  * This is an empty mainWindow that needs to be "specialized" for each possible

  *
  * It needs to defines some static constant fields :
  * - zeroValue : the zero for this numerical type
  * - unitValue : the maximum value of the normal dynamic range
  * - max : the maximum value
  * - min : the minimum value
  * - epsilon : a value close to zero but different of zero
  * - bits : the bit depth
  *
  * And some types :
  * - compositetype the type used for composite operations (usually one with
  *   a higher bit depth)
  *
  * This class is specialized to handle the floating point bounds of the CMYK color space.
