Implement per-page paper sizes.

2006-05-05  Alexander Larsson  <alexl@redhat.com>

	* gtk/gtkprintoperation-unix.c:
	Implement per-page paper sizes.

	* gtk/gtkprintoperation.c:
	Implement per-page paper sizes for pdf output.
	Make gtk_print_operation_set_pdf_target() work again

	* tests/Makefile.am:
	* tests/testprint.c:
	* tests/testprintfileoperation.[ch]:
	Add more test code for printing support.
	This tests per-page paper sizes & orientation and
	deriving from GtkPrintOperation.
