// TODOs for BulletSim (for BSScene, BSPrim, BSCharacter and BulletSim)
// Does NeedsMeshing() really need to exclude all the different shapes?
// 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
// LinkSets
// Freeing of memory of linksets in BulletSim::DestroyObject
// Set child prims phantom since the physicality is handled by the parent prim
// Linked children need rotation relative to parent (passed as world rotation)
// Should prim.link() and prim.delink() membership checking happen at taint time?
// Test sculpties
// 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
// Parameterize BulletSim. Pass a structure of parameters to the C++ code. Capsule size, friction, ...
// Use event subscription times to reduce the number of events passed up (_subscribedEventMS)
// Implement the genCollisions feature in BulletSim::SetObjectProperties (don't pass up unneeded collisions)
