      Modifier and Type Field Description
      protected static short ARG_1_AND_2_ARE_WORDS
      If set, the arguments are words; otherwise, they are bytes.
      protected static short ARGS_ARE_XY_VALUES
      If set, the arguments are xy values; otherwise they are points.
      protected static short MORE_COMPONENTS
      Indicates at least one more glyph after this one.
      protected static short ROUND_XY_TO_GRID
      If set, xy values are rounded to those of the closest grid lines.
      protected static short USE_MY_METRICS
      If set, this forces the aw and lsb (and rsb) for the composite to be equal to those from this original glyph.
      protected static short WE_HAVE_A_SCALE
      If set, there is a simple scale; otherwise, scale = 1.0.
      protected static short WE_HAVE_A_TWO_BY_TWO
      There is a 2 by2 transformation that will be used to scale the component.
      protected static short WE_HAVE_AN_X_AND_Y_SCALE
      The x direction will use a different scale from the y direction.
      protected static short WE_HAVE_INSTRUCTIONS
      Following the last component are instructions for the composite character.
