-CURRENT PRIORITIES
+CURRENT PROBLEMS TO FIX AND/OR LOOK AT
 =================================================
-Use the HACD convex hull routine in Bullet rather than the C# version.  
-        Speed up hullifying large meshes.
+Vehicle buoyancy. Computed correctly? Possibly creating very large effective mass.
+    Interaction of llSetBuoyancy and vehicle buoyancy. Should be additive?
+    Negative buoyancy computed correctly
+Computation of mesh mass. How done? How should it be done?
+Script changing rotation of child prim while vehicle moving (eg turning wheel) causes
+        the wheel to appear to jump back. Looks like sending position from previous update.
 Enable vehicle border crossings (at least as poorly as ODE)
         Terrain skirts
         Avatar created in previous region and not new region when crossing border
         Vehicle recreated in new sim at small Z value (offset from root value?) (DONE)
-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.
 Linkset child rotations.
         Nebadon spiral tube has middle sections which are rotated wrong.
         Select linked spiral tube. Delink and note where the middle section ends up.
+Refarb compound linkset creation to create a pseudo-root for center-of-mass
+        Let children change their shape to physical indendently and just add shapes to compound
 Vehicle angular vertical attraction
 vehicle angular banking
 Center-of-gravity
 Vehicle angular deflection
         Preferred orientation angular correction fix
-when should angular and linear motor targets be zeroed? when selected?
-        Need a vehicle.clear()? Or an 'else' in prestep if not physical.
 Teravus llMoveToTarget script debug
         Mixing of hover, buoyancy/gravity, moveToTarget, into one force
         Setting hover height to zero disables hover even if hover flags are on (from SL wiki)
 limitMotorUp calibration (more down?)
 llRotLookAt
 llLookAt
-Avatars walking up stairs (HALF DONE)
-Avatar movement
-        flying into a wall doesn't stop avatar who keeps appearing to move through the obstacle (DONE)
-        walking up stairs is not calibrated correctly (stairs out of Kepler cabin)
-        avatar capsule rotation completed (NOT DONE - Bullet's capsule shape is not the solution)
+Convert to avatar mesh capsule. Include rotation of capsule.
 Vehicle script tuning/debugging
         Avanti speed script
         Weapon shooter script
 Move material definitions (friction, ...) into simulator.
-Add material densities to the material types.
-Terrain detail: double terrain mesh detail
 One sided meshes? Should terrain be built into a closed shape?
         When meshes get partially wedged into the terrain, they cannot push themselves out.
         It is possible that Bullet processes collisions whether entering or leaving a mesh.

 VEHICLES TODO LIST:
 =================================================
-Border crossing with linked vehicle causes crash
-        20121129.1411: editting/moving phys object across region boundries causes crash
-            getPos-> btRigidBody::upcast -> getBodyType -> BOOM
+LINEAR_MOTOR_DIRECTION values should be clamped to reasonable numbers.
