  3. Fix pixel order

    The  specification  says "...samples  are  packed  into bytes  with  the
    leftmost sample in  the high-order bits of a byte  followed by the other
    samples for the  scanline.". This was not followed which  lead to images
    using greyscale and  indexed colours with pixel width  smaller than full
    byte to have the order of pixels reversed within the byte reversed.
    Thanks to Samium Gromoff for the report and test case.

  1. Really invoke build-transparency-map when a tRNS chunk is present.

    tRNS method sets (TRANSPARENCY *PNG-STATE*) to some raw data
    representation depending on colour-type. Then it adds
    so (TRANSPARENCY *PNG-STATE*) will become a 2D-array
    before *png-state* is finished.
    The latter part (adding the postprocessor) was inside an incorrect
    WHEN form, requiring (COLOUR-TYPE *PNG-STATE*) to be 0 or 2. First,
    our COLOUR-TYPE is a keyword, not a byte (thus 0 and 2 correspond to
    :greyscale and :truecolor, respectively). Second,
    build-transparency-map is prepared to handle :indexed-colour images as
    well, and there are images where it's useful. Third, preceding ECASE
    will fail for any colour-type except :greyscale, :truecolor and
    Therefore it seems that no additional checks are needed here at all,
    and that's the assumption behind this patch.
