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.
