[poppler] pdftocairo - Updated Patches

curl is only used for input. pdftocairo outputs using fopen which 
doesn't support WebDAV. Or any URLs for that matter. So what it does is 
it looks for a subdirectory in the current folder called "http:" and 
then fails.

Failure is not good default behavior.

Ok, I tend to agree. But I am looking for input on how to make it 
robust? Perhaps looking for "://" and falling back to "cairoout" in that 
case would work. The dot-suffix cutoff does work reasonably well for 
local files.

Right now I mostly just don't want to waste too much time on this.

Cheers,

Stefan
