GDLuminanceSource
  This class is used to help decode images from files which arrive as GD Resource It does not support rotation.
GenericGFPoly
  Represents a polynomial whose coefficients are elements of a GF.
GF256
  This class contains utility methods for performing mathematical operations over the Galois Fields. Operations use a given primitive polynomial in calculations.

LuminanceSourceAbstract
  The purpose of this class hierarchy is to abstract different bitmap implementations across platforms into a standard interface for requesting greyscale luminance values.
