ed3e909282 some more fixes for btSoftBody:
+ use btBroadphaseProxy::AllFilter to collide with static and dynamic rigidbodies in broadphase
+ enlarge aabb for softbody in broadphase, otherwise misses collisions (deformation is not updated in-time?)

b37a37a28e Added initial broadphase support for softbody versus softbody and softbody versus rigidbody (see btSoftSoftCollisionAlgorithm and btSoftRididCollisionAlgorithm)
Added 	SOFTBODY_SHAPE_PROXYTYPE.
Some refactoring for btSoftBody, needs more work.

d4698cb3d5 Added SoftBody demo, contribution by Nathanael Presson. Will integrate into Bullet broadphase.
Added very basic drawTriangle for btIDebugDraw, useful for basic softbody visualization.
Added btGjkEpa2, contribution by Nathanael Presson. Improved version of EPA penetration depth computation, more suitable for multi-core/SPU (less memory usage). Note: btGjkEpa2 is not enabled by default currently.

65bb612598 - added quickSort to btAlignedObjectArray (has generally better performance then heapSort)
- replaced all usage of heapSort by quickSort
- finished btMultiSapBroadphase. Still some work to be done to increase performance (faster add/remove from child broadphases. 
  uses currently AABB tree to locate child broadphase (should use grid), and sorted array takes too much time.

a4e63aed00 - DemoApplication, debug text rendering was broken, glLoadIdentity() missing
- copy user data over to child shape
- added applied impulse to btManifoldPoint

f12f04fb97 optimization: only call solveGroup if there is some work: avoid virtual function call, its overhead can be excessive

d051e2eacb First commit of 2008, Happy New Year!
Add option to compile without btClock and without profiling: comment out USE_BT_CLOCK, and #define BT_NO_PROFILE
Fixed typo/case in #include "LinearMath/btQuickProf.h", in SpuParallelSolver.cpp
Removed unnecessary files from libxml CMakeLists.txt

17a214a2b3 - Added btRigidBodyConstructionInfo, to make it easier to set individual setting (and leave other untouched) during rigid body construction.
This was harder using default arguments. Thanks Vangelis Kokkevis for pointing this out.
- Fixed memoryleak in the ConstraintDemo and Raytracer demo.
- fixed issue with clearing forces/gravity at the end of the stepSimulation, instead of during internalSingleStepSimulation.
Thanks chunky for pointing this out: http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=1780
- Disabled additional damping in rigid body by default, but enable it in most demos. Set btRigidBodyConstructionInfo m_additionalDamping to true to enable this.
- Removed obsolete QUICKPROF BEGIN/END_PROFILE, and enabled BT_PROFILE. Profiling is enabled by default (see Bullet/Demos/OpenGL/DemoApplication.cpp how to use this).
User can switch off profiling by enabling define BT_NO_PROFILE in Bullet/src/btQuickprof.h.

947dc8d33d Moved the 'btRigidBody::clearForce' to the end of the stepSimulation, instead of in each substep.
Should help with this issue, reported here: http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=1601
We can optionally leave out the 'clearForces'.
Thanks everyone for the discussion.

c80d1532f6 made access to mesh interface more consistent, so btConvexTriangleMeshShape uses also 'getMeshInterface', similar to btTriangleMeshShape.

- removed SSE includes, added #incude <string.h> for memset in Extras/quickstep, thanks Eternl Knight
- disabled 16-byte alignement on btQuadWord class, it causes problems under PS3 Linux. Need to check out why.

eff4fe8ec8 more work on hashed pairmanager. growing doesn't work yet, so need to allocate enough room for the overlapping pairs in advance.
boxbox reports contact point in B, rather then average point
box, cylinder use halfextents corrected for scaling and margin. made the margin in this halfextents explicit in the 'getHalfExtentsWithMargin' and 'getHalfExtentsWithoutMargin'
integrated changed for ODE quickstep solver
replaced inline with SIMD_FORCE_INLINE
some minor optimizations in the btSequentialImpulseConstraintSolver

added cone drawing (for X,Y,Z cones)

0405ce278a use size_t instead of int, for allocator
added hashtable based PairManager, thanks Pierre Terdiman and Erin Catto
improved friction in 'cachefriendly' solver
moved 'refreshcontactpoints' into collision detection, instead of solver
avoid linear search for contact manifolds, by storing an index
ignore margin for sphere shape (its entire radius is already margin)
avoid alignment checks in BVH serialization, they don't compile on 64-bit architectures
made 'bomb' box more heavy
