REVISION SUMMARY
  This extends 'FilePrinter::printFile' by an optional
  parameter to specify whether or not to do scaling and passes
  the 'fit-to-page' to CUPS dependent on what is specified.
  If the parameter is not specified, the behaviour remains
  unchanged.
  
  If FilePrinter is used, The PDF generator now passes this
  option depending on the scaling mode was selected in the
  custom print options widget, which is therefore now enabled
  for non-rasterized printing as well.

TEST PLAN
  1. open a PDF document in Okular and open the print dialog
  2. go to the "PDF Options" tab
  3. verify that "Force rasterisation" is disabled, but the "Scale mode" combobox is active.
  4. test all the three options available in the "Scale mode" combobox do what they say
  5. Make sure the three options still work as expected for the "Force rasterisation" case.
