Owen Taylor a1fe2ac180 Add: - A ::retrieve_surrounding signal that asks the widget for context
Thu Nov  1 16:20:56 2001  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkimcontext.[ch]: Add:
	  - A ::retrieve_surrounding signal that asks the widget for
	    context around the insertion point.
	  - A ::delete_surrounding signal that asks the widget to
	    delete context aroudn the insertion point.
	  - gtk_im_context_set_context() for widgets to set context
	    around the insertion point in response to ::retrieve_context.
	  - gtk_im_context_get_context() for context to get context
	    around the insertion point

	* gtkmarshal.list: Add BOOL:INT,INT

	* gtk/gtkimmulticontext.c: Proxy the get_surrounding() /
	set_surrounding() methods, and the ::retrieve_surrounding /
	::delete_surrounding signals.

	* gtk/gtkentry.c gtk/gtktreeview.c: Hook up to the
	GtkIMContext::retrieve_surrounding / ::delete_surrounding
	signals.
