Moved gtk_text_view_update_im_spot_location() calls into an idle, fixes

2007-11-11  Yevgen Muntyan  <muntyan@tamu.edu>

	* gtk/gtktextview.c: Moved gtk_text_view_update_im_spot_location()
	calls into an idle, fixes #494776.
	GtkTextViewPrivate:im_spot_idle, do_update_im_spot_location(),
	queue_update_im_spot_location(), flush_update_im_spot_location(): new
	field and functions to queue the call;
	(changed_handler): call queue_update_im_spot_location() instead of
	gtk_text_view_update_im_spot_location();
	(gtk_text_view_key_press_event): flush the idle here.
