Get a customized info widget to show extra information of a proposal.
This allows for customized widgets on a proposal basis, although in general
providers will have the same custom widget for all their proposals and
@proposal can be ignored. The implementation of this function is optional.
If this function is not implemented, the default widget is a #GtkLabel. The
return value of gtk_source_completion_proposal_get_info() is used as the
content of the #GtkLabel.
