         #107883, Gustavo Giráldez

        * gtk/gtktextlayout.c (gtk_text_layout_emit_changed):
        Split out the case where we know we changed, and
        already dealt with our cached line being invalidated
        from external calls to gtk_text_layout_changed.

        * gtk/gtktextlayout.c (gtk_text_layout_changed):
        Check if the invalidate yrange intersects our
        cached line, and clear it if necessary.
