commit d2b904e13f7ee8df3dcd8fa6063168893a89f6ec
Author: Christian Persch <chpe src gnome org>
Date: Wed Dec 1 20:58:49 2021 +0100
libview: Split the unix printing impl from the export print operation
Make EvPrintOperationExport an abstract base class, and move the
unix printing specific code to a new EvPrintOperationExportUnix.
This is in preparation to creating a EvPrintOperationExportPortal
which implements the export operation via Portal.
