+// Adjust character capsule size when height is adjusted (ScenePresence.SetHeight)
+// Test sculpties
+// Compute physics FPS reasonably
+// Based on material, set density and friction
+// More efficient memory usage in passing hull information from BSPrim to BulletSim
+// Four states of prim: Physical, regular, phantom and selected. Are we modeling these correctly?
+//     In SL one can set both physical and phantom (gravity, does not effect others, makes collisions with ground)
+//     At the moment, physical and phantom causes object to drop through the terrain
+// Should prim.link() and prim.delink() membership checking happen at taint time?
+// Mesh sharing. Use meshHash to tell if we already have a hull of that shape and only create once
+// Do attachments need to be handled separately? Need collision events. Do not collide with VolumeDetect
+// Implement the genCollisions feature in BulletSim::SetObjectProperties (don't pass up unneeded collisions)
+// Implement LockAngularMotion
+// Decide if clearing forces is the right thing to do when setting position (BulletSim::SetObjectTranslation)
+// Does NeedsMeshing() really need to exclude all the different shapes?
