	Bug 339318 - Allow page rendering to (optionally) happen in a thread

	* gtk/gtk.symbols: API change
	* doc/reference/gtk/gtk-sections.txt: API change
	* gtk/gtkprintoperation-private.h
	* gtk/gtkprintoperation.h
	* gtk/gtkprintoperation.c: Adds 2 new functions
	   gtk_print_operation_set_defer_drawing()
	     - Sets up the GtkPrintOperation to wait for calling of
	       gtk_print_operation_draw_page_finish() from application. It can
	       be used for drawing page in another thread.
	       This function must be called in the callback of "draw-page"
	       signal.
	   gtk_print_operation_draw_page_finish()
	     - Signalize that drawing of particular page is complete.
	       It is called after completion of page drawing (e.g. drawing
	       in another thread).
	       If gtk_print_operation_set_defer_drawing() was called before,
	       then this function has to be called by application. In another
	       case it is called by the library itself.
