Controls the element depth. When using custom drawing of geometry or primitive shapes there is no reference to the orthogonal axis used with respect to the current _transformPlane. The element depth is in world-space and for each transform plan is defined as: Element depth is rendered along the Z axis when using PhysicsWorld.TransformPlane.XY. Element depth is rendered along the Y axis when using PhysicsWorld.TransformPlane.XZ. Element depth is rendered along the X axis when using PhysicsWorld.TransformPlane.ZY. You should set the element depth before performing any custom draw. The element depth will be reset to zero when rendering is complete.
