Transforms a point from the coordinate space of the scene into the local coordinate space of this Node. Note that if this node is in a SubScene, the arguments should be in the subscene coordinates, not that of javafx.scene.Scene.

Parameters:

sceneX		x coordinate of a point on a Scene
sceneY		y coordinate of a point on a Scene
sceneZ		z coordinate of a point on a Scene

Returns:  local Node's coordinates of the point or null if Node is not in a Window. Null is also returned if the transformation from local to Scene is not invertible.

Since:  JavaFX 8.0
