JDK-8116798 - Event local coordinates are wrong with perspective camera
Description
If any node has Z != 0 (either a 3D shape or 2D node transformed out of the XY plane), with parallel camera the node is either not picked at all, or is picked in a wrong area and with wrong local coordinates.

This issue is closely related to RT-24646 (3D-picking) and RT-28129 (local 3D coordinates with perspective camera).

Fixed by changesets b1e1caf6c52d (rt) and 449dc17bc8de (rt-closed).

The push 897ef4f2b18e (see RT-5475) should eliminate any significant slowdown caused by switching to the 3D picking.
18-02-2013
The most natural solution is to merge the two existing picking approaches and use the 3D pick-ray-based picking for parallel camera.
