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
#GtkIMContext::retrieve-surrounding and records the context received
by the subsequent invocation of @get_surrounding.
