Converts a point in the coordinate system of this node's parent to screen space
<p>
This method assists in converting points to screen space in situations where this
node may be the root node, in which case getParent() is not available, and therefore,
you cannot simply do:

<pre>
 this.getParent().convertPointToScreen(p)
</pre>

@param point The relatable point to convert, in this node's parent's coordinate system
@return The converted point in screen space
