+Lock axis
 Deleting a linkset while standing on the root will leave the physical shape of the root behind.
 	Not sure if it is because standing on it. Done with large prim linksets.

 GENERAL TODO LIST:
 =================================================
+Resitution of a prim works on another prim but not on terrain.
+	The dropped prim doesn't bounce properly on the terrain.
 Add a sanity check for PIDTarget location.
 Level-of-detail for mesh creation. Prims with circular interiors require lod of 32.
 	Is much saved with lower LODs? At the moment, all set to 32.

-Use the HACD convex hull routine in Bullet rather than the C# version.
 Do we need to do convex hulls all the time? Can complex meshes be left meshes?
 	There is some problem with meshes and collisions
 	Hulls are not as detailed as meshes. Hulled vehicles insides are different shape.
