 /** \class SkXfermode
  *
  *  SkXfermode is the base class for objects that are called to implement custom
  *  "transfer-modes" in the drawing pipeline. The static function Create(Modes)
  *  can be called to return an instance of any of the predefined subclasses as
  *  specified in the Modes enum. When an SkXfermode is assigned to an SkPaint,
  *  then objects drawn with that paint have the xfermode applied.
  *
  *  All subclasses are required to be reentrant-safe : it must be legal to share
