Hi Ian,
in the case where a user clicks on a pseudo text input on the canvas, can a
focus rectangle be drawn using the drawfocusring() method?

would it not make sense for click to cause the associated
(drawfocusring(element, ) text input in the subdom to gain focus?
Thus the drawfocusring() method could be used to cut down on unecessary
duplication of event handling for all users as they would be handled by the
native elements regardless of whether they had a disibility and required the
use of the keyboard or not.
