    Optionally write uncompressed PDF files
    
    Adapted Vadim's suggestion here:
      http://lists.nongnu.org/archive/html/lmi/2018-02/msg00063.html
    to write uncompressed PDF files, iff "--pyx=uncompressed_pdf" is
    specified on the command line. Compression remains the default, as
    always.
    
    A single, simple, default illustration PDF created thus:
      Ctrl-N I Enter Ctrl-I
    was 26386 bytes with compression, and 158922 without: six times as
    large.
    
    BTW, "--pyx" options may be combined, e.g.:
      --pyx=only_new_pdf,uncompressed_pdf
