<pre>I'm a little bit confused about it:
1. If I parse the PDF of <a href="show_bug.cgi?id=95061#c2">comment 2</a> i.e. with /utils/pdftoppm -png -f 1 -l 1
-cropbox I don't get any error messages.
2. The main stream of a PDF always starts with offset 0
3. The PDF spec says about the H entry in the "Linearization Parameter
Dictionary": offset1 shall be the offset of the primary hint stream from the
beginning(!!!) of the file.
4. All offsets in poppler, i.e. also the xref offets, are offsets from the
beginning of a file and never add some hypothetical offet of substreams</pre>
