Open a 2D drawing area specified by the <b>size</b> field. Children nodes out of this
area will not be visible (they will be <i>clipped</i>).<br/>
The position origin of the area is the result of above transformations.

<b>Note:</b><br/>Only use <a href="development_node_Layer2D.html">Layer2D</a>
if you need to clip the children nodes. Otherwise, just use a
