/**
|
|
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_
|
|
method and use that for your drawing code.
