1) Should the library set the compression mode of the document on
input?  The result of doing this would be that, if no action were
taken by the user, if an input document (which was compressed) were
written out it would be written as a compressed file (rather than
uncompressed as now).

2) If the library is to set the mode as compressed, what "mode"
should be used (and if anyone knows how I can determine the original
compression mode of the input file, please advise)?  Is it better to
set it as "1" (minimum compression), or "9" (maximum compression),
or some other value?  Bear in mind that the user can always override
whatever default mode is set.
