/**
* gnome_print_pango_update_context:
* @context: a #PangoContext from gnome_print_pango_create_context().
* @gpc: a #GnomePrintContext
*
* Update a context so that layout done with it reflects the
* current state of @gpc. In general, every time you use a
* #PangoContext with a different #GnomePrintContext, or
* you change the transformation matrix of the #GnomePrintContext
* (other than pure translations) you should call this function.
* You also need to call pango_layout_context_changed() for any
* #PangoLayout objects that exit for the #PangoContext.
*
* This function currently does nothing and that isn't expected
* to change for gnome-print. The main benefit of calling it
* is that your code will be properly prepared for conversion
* to use with future rendering systems such as Cairo where
* the corresponding operation will actually do something.
