Translates a 2D point from NDC (<em>Normalized Device Coordinates</em>) to a [page:Raycaster] that can be used for picking. NDC range from [-1..1] in x (left to right) and [1.0 .. -1.0] in y (top to bottom).
[page:Camera camera] — camera to use in the projection.<br/>
[page:Boolean sort] — select whether to sort elements using the <ahref="http://en.wikipedia.org/wiki/Painter%27s_algorithm">Painter's algorithm</a>.
