      Inverting color format order (RGB->BGR or BGR->RGB)
      In the case of enabling this option, API reports pixel-format in capabilities
      as the inverted value of the RGB pixel-format specified in MADCTL.
      This option is convenient for supporting displays with bugs
      where the actual color is different from the pixel format of MADCTL.
