[poppler] patch to make selection works with rawOrder

[Daniel Garcia Moreno]

I've modified my patch to works as normal when !rawOrder and when
TextOutputDev.rawOrder makes selection with "raw" algorithm.

This solution doesn't break current one and adds new functionality to
poppler.

What do you think about it?, it's unneeded or it's a good feature to add
to poppler? I think it's useful, because I do it :P and because it works
for me...
