[poppler] Poppler and 16 bit images, workaround or not?

[Albert Astals Cid]

Hi, poppler is not prepared at all for 16 bits per component images, 
everywhere it assumes a component of the color fits into a Guchar (8 bits).

You can see the consequences with the pdf present at 
http://bugs.kde.org/show_bug.cgi?id=158165

I have attached a 5 line patch that "fools" poppler and makes it use the high 
8 bits and discard the other 8.

This makes it "work" but it's obviously a workaround and not the real solution 
and i have only this pdf using 16 bits per component and it's really a "test 
document" not a real one.

So i'm hesitating if incorporating the patch (with comments explaining the 
workaround) or not doing it.

Comments?

Albert
