    Resolves: tdf#100838 no transparency support on using original jpg data path
    
    This became a problem since...
    
    commit 76ec54e8c9f3580450bca85236a4f5af0c328588

        tdf#97662 - Try to preserve original compressed JPEGs harder.
    
        Avoiding de-compressing and re-compressing them saves lots of time too.
    
    for the default JPEG Compress + Reduce Image resolution case
    
    but appears to always be a problem with the Lossless - Reduce Image 
resolution
    case.
