/**
  Convert a *.BMP graphics image to a GOP blt buffer. If a NULL Blt buffer
  is passed in a GopBlt buffer will be allocated by this routine. If a GopBlt
  buffer is passed in it will be used if it is big enough.

  @param  BmpImage      Pointer to BMP file
  @param  BmpImageSize  Number of bytes in BmpImage
  @param  GopBlt        Buffer containing GOP version of BmpImage.
  @param  GopBltSize    Size of GopBlt in bytes.
  @param  PixelHeight   Height of GopBlt/BmpImage in pixels
  @param  PixelWidth    Width of GopBlt/BmpImage in pixels

  @retval EFI_SUCCESS           GopBlt and GopBltSize are returned.
  @retval EFI_UNSUPPORTED       BmpImage is not a valid *.BMP image
  @retval EFI_BUFFER_TOO_SMALL  The passed in GopBlt buffer is not big enough.
                                GopBltSize will contain the required size.
  @retval EFI_OUT_OF_RESOURCES  No enough buffer to allocate.
