+ * It might be nice to be able to trap I/O errors separately from
+   other errors; especially be able to separate errors that the user
+   can fix (like permission errors) from errors that they probably
+   can't fix like corrupted PDF files, unsupported filters, or
+   internal errors.  However, only QPDF::processFile(), which does the
+   initial read, and QPDFWriter::QPDFWriter(), which does the initial
+   write, are at all likely to generate such errors for a case other
+   than a catastrophic failure.

  * See whether we can do anything with /V > 3 in the encryption
    dictionary.  (V = 4 is Crypt Filters.)
