Yeah, good catch - but maybe we should fix this by removing more of our 
xpdfrc dependency: either always fall back to (0, 0) - (width, height) 
or let the user specify the visible area.  Adding more parameters to the 
PSOutputDev constructor scares me a bit though, maybe there's a better 
way to do it.
