Add gtkprintoperationpreview.[ch] Set default preview command. Hardcoded
2006-06-02 Alexander Larsson <alexl@redhat.com> * gtk/Makefile.am: Add gtkprintoperationpreview.[ch] Set default preview command. Hardcoded for now. * gtk/gtkmarshalers.list: Add BOOLEAN:OBJECT,OBJECT,OBJECT * gtk/gtkprintbackend.c: Add preview command property. * gtk/gtkprintcontext.[ch]: Make less dependent on PrintOperation for output settings Externally set cairo_t and dpi. Resettable. Create fontmap without metrics hinting (so that print preview text layout doesn't depend on zoom level). * gtk/gtkprintoperation-private.h: * gtk/gtkprintoperation-unix.c: * gtk/gtkprintoperation.[ch]: Initial work on print preview API and default implementation using an external preview app. * gtk/gtkprintoperation-win32.c: Some needed updates. Not done, needs more work. * gtk/gtkprintoperationpreview.[ch]: New interface used in print preview api. * gtk/gtkprintunixdialog.c: Add print preview dialog. * tests/print-editor.c: Test using an custom print preview widget.
