        fdo#66006 Convert to PNG for JPEG that can't be losslessly rotated

        If a JPEG image has a width or height which is not a multiple of 16
        (width/heigh % 16 != 0) then it can't be completelly lossleessly
        rotated (the last uncomplete MCUs can't be rotated) and the image
        is cropped on the lower size. To prevent this such JPEG images
        must be rotated to PNG to prevent loss. Afterwards image can still
        be compressed with "Compress Graphic Dialog".

Probably not a bug, but a feature - converting to PNG takes some time.
