/**
  Prints a formatted ASCII string to a graphics console device specified by 
  ConsoleOutputHandle defined in the EFI_SYSTEM_TABLE at the given (X,Y) coordinates.

  This function prints a formatted ASCII string to the graphics console device 
  specified by ConsoleOutputHandle in EFI_SYSTEM_TABLE and returns the number of 
  ASCII characters displayed, not including partial characters that may be clipped 
  by the right edge of the display.  If the length of the formatted ASCII string is
  greater than PcdUefiLibMaxPrintBufferSize, then at most the first 
  PcdUefiLibMaxPrintBufferSize characters are printed.The EFI_HII_FONT_PROTOCOL
  StringToImage() service is used to convert the string to a bitmap using the glyphs 
  registered with the HII database. No wrapping is performed, so any portions of the 
  string the fall outside the active display region will not be displayed. Please see 
  Section 27.2.6 of the UEFI Specification for a description of the supported string
  format including the set of control codes supported by the StringToImage() service.

  If a graphics console device is not associated with the ConsoleOutputHandle 
  defined in the EFI_SYSTEM_TABLE then no string is printed, and 0 is returned.
  If the EFI_HII_FONT_PROTOCOL is not present in the handle database, then no 
  string is printed, and 0 is returned.
  If Format is NULL, then ASSERT().

  @param  PointX       X coordinate to print the string.
  @param  PointY       Y coordinate to print the string.
  @param  ForeGround   The foreground color of the string being printed.  This is
                       an optional parameter that may be NULL.  If it is NULL,
                       then the foreground color of the current ConOut device
                       in the EFI_SYSTEM_TABLE is used.
  @param  BackGround   The background color of the string being printed.  This is
                       an optional parameter that may be NULL.  If it is NULL, 
                       then the background color of the current ConOut device
                       in the EFI_SYSTEM_TABLE is used.
  @param  Format       Null-terminated ASCII format string.  See Print Library 
                       for the supported format string syntax.
  @param  ...          Variable argument list whose contents are accessed based on 
                       the format string specified by Format.         

  @return  The number of ASCII characters printed.
