3e2529fcb5 Minor constraint refactoring, to allow SPU-side processing for PLAYSTATION 3 (added non-virtual methods)
Also comment-out some code for __SPU__ to reduce code size
Added btContactConstraint (only used on PS3 SPU right now, better to use btPersistentManifold directly for contact constraints)
Improved readblend utility library (see also usage in http://gamekit.googlecode.com with Irrlicht)

Fix for btConvexConvexAlgorithm, potential division by zero

f552a1dbbf Remove first argument from btMultiSphereShape, calculate local inertia approximation from aabb.
If user wants more accurate inertia tensor for multi-sphere shape, use btCompoundShape instead 
(amd btCompoundShape::calculatePrincipalAxisTransform)

6c80353556 Minor fix in friction: calculate second friction direction based on un-scaling first friction direction (issue if it was scaled to zero)
Force activation state of static objects to be ISLAND_SLEEPING, once they are added to the world

258ef6e25a + Added joint feedback for constraints, needs testing/demo before 2.75 release.
See also http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=2677
and http://code.google.com/p/bullet/issues/detail?id=227

To enable, use constraint->enableFeedback(true);
And then either use
constraint->getAppliedImpulse() for an estimated applied impulse,
or constraint-> getAppliedLinearImpulse(), or constraint->getAppliedAngularImpulseA() or constraint->getAppliedAngularImpulseB().

+removed a few warnings.

Thanks Ole for the report and suggested fix:
http://code.google.com/p/bullet/issues/detail?id=220&can=1&start=200

Applied Character/btKinematicCharacterController.cpp patch:
Thanks Thomas for the patch!
http://code.google.com/p/bullet/issues/detail?id=196#makechanges

 - added a normalizedDirection member variable.  This is
     slightly more efficient than recalculating the normalized
     direction every simulation step.

 - I overloaded the m_walkDirection member variable to hold
     either the walkDirection or the Velocity, and used a boolean
     flag to determine which behavior was required.

 - The normalization behavior seemed custom, and I needed it
     twice, so I moved it to a static helper method.

 - I added the setVelocityForTimeInterval() method to the
     base interface class.  This to me is the scariest change
     since people inheriting from it will need to make changes
     (if only to add an empty function).

700db838b1 Add 1D and 2D support for Bullet: using rigidbody->angularFactor(const btVector3& factor) and body->setLinearFactor(const btVector3& linearFactor);
For example, to only allow linear motion in the X-Z plane, and only rotation around Y axis use:
	body->setLinearFactor(btVector3(1,0,1));
	body->setAngularFactor(btVector3(0,1,0));

90f96aec27 Introduced btActionInterface. This makes it easier to extend user-defined actions, such as vehicles and characters.
btRaycastVehicle and btKinematicCharacterController are derived from btActionInterface now.

459c22e7cb Synchronized changes of Bullet, from Blender.
Added optional flag btSoftBody::appendAnchor(	int node,btRigidBody* body, bool disableCollisionBetweenLinkedBodies=false), to disable collision between soft body and rigid body, when pinned
Added btCollisionObject::setAnisotropicFriction, to scale friction in x,y,z direction.
Added btCollisionObject::setContactProcessingThreshold(float threshold), to avoid collision resolution of contact above a certain distance.
Avoid collisions between static objects (causes the CharacterDemo to assert, when a dynamic object hits character)

210fe36106 Add backface culling and option to keep unflipped hit normal in case a ray hits a back-facing triangle.
Usage: set RayResultCallback.m_flags to kF_FilterBackfaces, optionally combined with kF_KeepUnflippedNormal.
Thanks Andy O'Neil for the patch!

Remove the force_inline for some internal constraint solver methods, it makes re-use easier.
