D28193: [KFontChooser] Use one QFontDatabase object for the ::Private class

[David Faure]

dfaure added a comment.


  I don't think this makes any difference, they all share the same underlying private singleton.
  So all this does is to use a tiny bit more memory while the widget is up (the member var).
  The additional CPU usage without this patch or the additional memory usage with this patch are both negligible, so I can't really say which way is best.
