      Description

      At the moment, lcms glue code falls back to processing images in java, if destination image has alpha channel. It is done because lcms does not thrasher non-color channels from source to destination.
      Unfortunately, this approach hits performance.
      We have to investigate whether there is an option to improve performance of color conversion for
      images with alpha channel
