Get the GtkTextIter at which the completion for proposal starts. When
implemented, this information is used to position the completion window
accordingly when a proposal is selected in the completion window. The
proposal text inside the completion window is aligned on iter.
If this function is not implemented, the word boundary is taken to position
the completion window. See gtk_source_completion_provider_activate_proposal()
for an explanation on the word boundaries.
When the proposal is activated, the default handler uses iter as the start
of the word to replace. See
gtk_source_completion_provider_activate_proposal() for more information.
