Called via gtk.imcontext.IMContext.getSurrounding to update
the context around the cursor location. It is not necessary to override this
method even with input methods which implement context-dependent behavior.
The base implementation emits signal@Gtk.IMContext::retrieve-surrounding
and records the context received by the subsequent invocation of
vfunc@Gtk.IMContext.get_surrounding.
