/**
	_enyo.canvas.Shape_ is the base kind for shapes that can be drawn into the
	canvas.	It doesn't have a default rendering, but an event handler may call
	the _draw_ method on it.

	Kinds derived from this one should provide their own implementation of
	_renderSelf_. If more complex operations are needed for filled mode or
	outline	mode, override the _fill_ or _outline_ methods, respectively.
