When including a pdf with viewport, pdflatex gives following error:

! Package graphics Error: Division by 0.

One can reproduce the issue with following commands:

pdflatex pax-include
pdflatex pax-include
perl C:\MiKTeX\scripts\pax\pdfannotextractor.pl pax-include
pdflatex pax-demo

When using the above fix, the example compiles fine.

Thank to Heiko Oberdiek for the fix.
