Merging QAbstractPrintDialog with QPrintDialog, as proposed in the
removed comment, seems to have little value, given that the platform
specific implementations rely on the current abstraction.
Adjust examples and tests; with the QAbstractPrintDialog test now
testing the QPrintDialog::options API, the corresponding test function
can be removed from the QPrinter test.
