that's great to hear.  I'll you know once the complete interface-changing
patch is done.

If you want to migrate your own code to std::unique_ptr then maybe
the #ifdefs can even be avoided, because code like

   auto foo = std::unique_ptr<Foo>( popplerMethod() );

should work no matter whether the pointer returned by popplerMethod
is plain-C or unique_ptr.

Best regards,
Oliver
