   *
   * Description: These #defines are used in the PC_Disp???() functions.  The 'color' argument in these
   *              function MUST specify a 'foreground' color and a 'background'.
   *              If you don't specify a background color, BLACK is assumed.  You would
   *              specify a color combination as follows:
   *
   *              PC_DispChar(0, 0, 'A', DISP_FGND_WHITE + DISP_BGND_BLUE);
   *
   *              To have the ASCII character 'A' with a white letter on a blue background.
