* Warning! Physics API change. This means that the NBodySimulation needs to be updated!
* PhysicsActor -> void SetVolumeDetect(int) needs to go into classes that use PhysicsActor as their base class.
* This is a HUGE OMG update and will definitely have unknown side effects.. so this is really only for the strong hearted at this point. Regular people should let the dust settle.
* This has been tested to work with most basic functions. However.. make sure you back up 'everything' before using this. It's that big!
* Essentially we're back at square 1 in the testing phase.. so lets identify things that broke.
* Currently if you apply that to only one or two axis you get unpredictable and sometimes explosive results.
* Three axis works well enough to play with it anyway. More work is needed here.
* Fixed an incorrectly named method in ODE.NET
* It doesn't generate at_target events, because they don't exist yet in the script engine.
* The Tau is different, however, compatible with scripts I tested.
* Not perfect... but pretty good.
* Added osSetPrimFloatOnWater(BOOL) to make Physical prim float at the water level.
* osSetPrimFloatOnWater(TRUE); or osSetPrimFloatOnWater(FALSE);
* By default, prim do not float at the water level.
* More work is needed on the floating, but it's a start.
* To play with this you must link your prim before setting it physical, otherwise they won't link in the physics engine properly. This will also be fixed.
* Currently the linked prim are extremely unstable because I have yet to implement combining of forces with the same normal. This will also be fixed. In fact, the whole PhysicsActor, ODEPrim relationship will be reworked to consider groups from the get-go.
* This implementation is better then it crashing your sim, so I'm commiting it for now.
* When you select a physical prim, it stops while you've got it selected.
* When you move or alter a prim in some manner, it doesn't become collidable until you de-select it
* When you select a prim, it doesn't become temporarily 'phantom' until you make some change to it while it's selected. (this prevents accidental selections in prim floor from causing it to go phantom on you(but don't move it or you'll fall))
* There's one major difference, and that's a physical object won't stop if you don't have permission to edit it. This prevents people who don't have edit permissions on a prim from stopping it while it's moving.
* Updated the ode.dll for windows with a more reasonable stack space reserve. Linux users will need to type ulimit -s 262144 before starting up OpenSimulator if using Physical Prim to protect against stack collisions. or run the included ./bin/opensim-ode.sh to start up OpenSimulator in ODE mode.
* Added internal collision score and am keeping track of 'high usage' prim.
* Tweaked collisions some more
* Tested up to 460 physical prim in extremely close quarters (which was previously impossible in OpenSim). After 460 in tight quarters, physics slows down enough to make it hard to do any moving, however.. non physics things still work, such as logging on to the simulator, etc.
* Exposed the mass as a PhysicsActor read only property (so scripts can get at it - hint hint -)
* Hollow and Path Cuts affect the prim mass (all Hollow Types are supported in this calculation (sphere,square,triangle))
* Prim no longer sink into the ground.
* ODE - Fixed the iscolliding property to report a static true when colliding.
* Added reporting of collisions to call UpdateMovementAnimations
* Added Jump - air animation (with arms outstretched).
* Added Fall Animations
* ODE - Added a small amount of X, Y motion control while jumping or Falling
* ODE - Avatar movement animations are still a bit odd sometimes, and had to get this up there.
* Added a ThrottleUpdates member to PhysicsActor to expose 'throttle' ability to the Scene.
* Updated the ode.dll file with a fix to invalid data passed to ODE's heightfield collision calculator.
