D25006: Make sure -dpi value is valid

[David Edmundson]

  Turning a number into a string and back again isn't ideal
  
  I would suggest:
  
    int dpiValue = dpiConfigGroup.readEntry("forceFontDPI", -1);
    
    
    if (dpiValue  > 24) {
         const QString dpiArgument = QStringLiteral("-dpi ") + 
QString::number(dpiValue);
        args[QStringLiteral("kde_settings.conf/X11/ServerArguments")] = 
dpiArgument;
    }
  
  Though I'm not sure I fully understand why we have this sort of wrong value 
in the config anyway?
  
  Also do we want
  
    } else {
            args[QStringLiteral("kde_settings.conf/X11/ServerArguments")] = 
QString();
    }
  
  so that a broken DPI wipes the old config entry out? Not sure.
