D5487: Set xrdb XFT.DPI value as integer

REVISION SUMMARY
  QXcbScreen when loading uses QByteArray.toInt().
  
  QByteArray("152.23").toInt() returns 0, rather than a rounded version,
  this means QXcbScreen falls back to the virtualDPI for the logicalDPI
  rather than the explicitly set one.
  
  The end result is that my scaling setting didn't work properly.
