    libgimpwidgets: small details to better sync with `master` branch.
    
    The gimp-2-10 patch contributed as !514 was slightly different from the
    master one as !515, especially since the last one got the reviews. This
    syncs the 2 codebases (making it easier to backport future patches on
    the same piece of code) and do a few fixes.
    
    - Syncing alignments.
    - Fix a comment.
    - Use g_build_filename() for properly creating paths rather than string
      concatenations.
