Allow the GtkTextView input method to internally handle key press
and release events. If this function returns TRUE, then no further
processing should be done for this key event. See
gtk_im_context_filter_keypress().
Note that you are expected to call this function from your handler
when overriding key event handling. This is needed in the case when
you need to insert your own key handling between the input method
and the default key event handling of the GtkTextView.
Since 2.22
