c1c01ff1a0 Use btContinuousConvexCollision instead of btGjkConvexCast (has issues in btCollisionWorld::objectQuerySingle) 
Fixes in btHeightfieldTerrainShape, thanks Jay Lee.

513a055035 Use proper rotation for computing local aabb for convex cast shape. 
Propagate hit point from convex caster to world callback [work in progress].

6f80b98a67 - fix issue with convex cast: results further away (larger hitfraction) could overwrite closer results 
- minor naming convention thing (variables start with lower case)
- renamed MotorDemo
- added ConcaveConvexcastDemo, Thanks John McCutchan (JMC)

e252f5cadd Bugfix: allow btCollisionObjects (non-btRigidBody) to interact properly with btRigidBody for cache-friendly btSequentialImpulseConstraintSolver. 
Thanks Andy O'Neil for pointing this out.

ec76f2e0a3 - keep track of all memory allocations (gNumAllignedAllocs/gNumAllignedFree) 
All memory allocations in Bullet go through btAlignedAlloc/btAlignedFree

ea3dfb4ca3 made 'calculateLocalInertia' const, thanks to cgripeos, see http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=1514 
- applied a large patch to remove warnings
Thanks to Enrico, see http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=1568
- 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

b054f375bc - Added serialization to btBvhTriangleMeshShape/btOptimizedBvh. See ConcaveDemo for example usage. 
- added bt32BitAxisSweep3, which co-exists without recompilation, using template class. This broadphase is recommended for large worlds with many objects (> 16384), until btMultiSwap is finished.
- Fixed some recent issues in Bullet 2.57 related to compound (thanks Proctoid) and memory allocations

87df3d0f32 Based on feedback from another professional game company, there are several improvements, including some API change... 
Some dynamic memory allocations have been replace by pool allocation or stack allocations.
quantized aabb versus quantized aabb overlap check is made branch-free (helps a lot on consoles PS3/XBox 360)
Collision algorithms are now created through a new btDefaultCollisionConfiguration, to decouple dependency (this is the API change):
Example:
	btDefaultCollisionConfiguration* collisionConfiguration = new btDefaultCollisionConfiguration();
	m_dispatcher = new	btCollisionDispatcher(collisionConfiguration);

30b1887f40 added configuration files for collision detection. 
this allows to use different collision algorithms by default, and avoid linkage issues.

1f7646f72a Refactoring to enable multi SAP broadphase. 
This was already planned, and Pierre Terdiman recent thread motivated me to decouple the paircache from the sweep and prune.

bf967a458a applied patches from Marten (Starbreeze) for per-rigidbody sleeping thresholds, access to constraint references. 
Also added assert, to make sure users don't delete rigidbodies while constraints point to them.

685138d033 include paths should not be relative starting with "../ 
It leads to problems with certain compilers, when Bullet/src is located in a long pathname.
Keep include path starting with "LinearMath/, "BulletCollision/, or "BulletDynamics/

3ad4316622 the relative path #include gives troubles in some cases. 
I need to revert all those back (after Steve Bakers changes a while back).
All includes should really be relative to the 'src' folder, or wherever the developer copies all the headerfiles.

c791a3192c In the copy constructor initializer list of LocalRayResult in 
btCollisionWorld.h  line 139 (version 2.48) it reads:
m_localShapeInfo(m_localShapeInfo),
which should be:
m_localShapeInfo(localShapeInfo),

054d672592 - removed STL from the Bullet library: replace std::vector by btAlignedObjectArray. Also removed the std::set for overlapping pair set, and turned it into an overlapping pair array. The SAP only adds objects, never removed. Removal is postponed for during traversal of overlapping pairs (duplicates and non-overlapping pairs are removed during that traversal). 
- added heap sort and binary search/linear search to btAlignedObjectArray
- fixed wrong cast, thanks Hamstray, http://www.continuousphysics.com/Bullet/phpBB2/viewtopic.php?t=1015
