last minute changes :
- Landscape Normals were INVERTED from the start

:o this has been fixed...... And normals smoothing has been improved also, logically no more "strip" should appear in your lighting.
-> Conclusion : Remember to reverse your light direction for the landscape now, it should always be with a negative y if you want the land to be lit.
- MousePicking for Billboard fixed (all 3 modes, no mode was working)
- scene.MousePicking for Actor2 fixed also :p (on error resume next was blocking the test heh)
- Snooker, Shoot In the mountain, isometric camera samples fixed.
- lots of small things.
