[poppler] [PATCH] pdftocairo rotation different than pdftops

[Adrian Johnson]

I don't understand what the problem is or how this patch helps. I
applied the patch and ran:

 pdftocairo -ps rotated0.pdf out.ps

Viewing out.ps with gv the page is upside down. Viewing with evince seg
faults with "attempt to allocate widget with width -36 and height 15".

Using pdftops or pdftocairo without the patch both gv and evince display
the page correctly.
