[poppler] Memory leak in SplashOutputDev::axialShadedFill

[Thomas Freitag]

Hi!

Using valgrind with the well known ducks & roses I encountered, that I 
forgot do delete the pattern object in SplashOutputDev::axialShadedFill, 
so the correct last statements should be:

:    :    :
   delete pattern;
   delete path;

   return retVal;
}
