Okay, here it is. In a few places it has already a similar 
implementation than in bug 50992 (thread safe), because changing the 
overprint option also meant that we need a different SplashOutputDev 
instance. But You probably also want to test it in okular? Even if we 
are here not on an okular list, I attach the okular patch here, too. 
Also here, it has already the changes from bug 50992. But because 
POPPLER_QT_THREADSAFE is not defined here, it doesn't make any 
difference, so I let these changes as they are. BTW, I'm not really 
familiar with qt programming, so most changes in okular are more or less 
a (hopefully) best guess.
