Regarding a reversed, multiple sheets per page bug

[Alex Tsui <alextsui05 gmail com>]

Specifically, I'm referring to this bug:

http://bugzilla.gnome.org/show_bug.cgi?id=582866

I've been able to reproduce it with a git copy of evince (2.27.1) by
printing to PDF.  Judging from the description and comment, the
negative increment used in ev-print-operation is basically
inappropriate since for anything other than a single page per sheet
will have reversed contents.  This is unexpected, according to the bug
report, and I wanted to confirm that it is with a developer.

A workaround that I had in mind was to print a document with the
desired pages per sheet and in order at first.  From this intermediate
document, print to PDF again, this time with one page per sheet and in
reversed order.  This gives the correct order at the end.  Maybe this
two-step process could be turned into code to deal with the reversed,
multiple sheets per page case.  Does this seem to be a acceptable fix
to pursue?
