/**
	The base kind for items that live inside an
	<a href="#enyo.Canvas">enyo.Canvas</a> control.

	If you're using this kind directly, you may implement an _onRender_ event
	handler in the owner to handle drawing into the canvas.

	If you're deriving a new kind based on this one, override the _renderSelf_
