[poppler] regression rendering selection in TextOutputDev (evince)

[Albert Astals Cid]

0.78 has a regression in rendering of selection.

I fixed it yesterday and was hoping to release 0.79 today but didn't get time and i'm going to be AWOL for 4/5 days, so anyone shipping 0.78 may want to distro patch https://cgit.freedesktop.org/poppler/poppler/commit/?id=2d191b49ea074cc69ba4c68a572f26c8bdb55abd until we get 0.79 out.

Cheers,
  Albert
