07b577fd86 make debugDrawWorld virtual for btSoftRigidDynamicsWorld
Move btSoftBodyWorldInfo to public, instead of nested, so it can be easier forward declared.
See http://code.google.com/p/bullet/issues/detail?id=78

Add get methods for damping/thresholds, see http://code.google.com/p/bullet/issues/detail?id=77

1c0fa00bc7 + provide access to 'root' collision shape, in case the original collision shape is temporarily replaced by a child collision shape.
+ added MultiMaterialDemo showing how to use the new btTriangleIndexVertexMaterialArray.
Thanks to Alex Silverman for this contribution!

f8e5481612 Added method to collect all persistent contact manifolds, given a btBroadphasePair (collision algorithm)
virtual	void	getAllContactManifolds(btManifoldArray&	manifoldArray)
See Demos/CharacterDemo/CharacterDemo.cpp for example usage of getAllContactManifolds
Added btDbvtBroadphase to btBulletCollisionCommon.h headerfile
Enable soft body vs concave (albeit slow)
Improved contact point debug rendering (moved from constraint solver into debugDrawWorld)

bd97c5e569 Fixed warnings in Bullet/src core library
Thanks Martijn Reuvers from Two Tribes B.V. (www.twotribes.com) for the patch

To make this work more visible, suppress warnings in external libraries in Extras (COLLADA_DOM, libxml and glui contain many warnings)
Added PreprocessorDefinitions: _CRT_SECURE_NO_DEPRECATE;_CRT_NONSTDC_NO_DEPRECATE to vcproj files

1139c06a4d more soft body preparations, moved some parts from Demo/SoftBody to src/BulletDynamics/SoftBody
moved Extras/ConvexHull/btConvexHull.* to src/LinearMath/btConvexHull.*
removed btCollisionObject::m_internalOwner, replaced it by m_internalType. This should not affect external API (it was clearly marked as internal)

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
- add ContactProcessedCallback (needs test/demo)
- didn't copy over m_additionalDampingFactor into btRigidBody.

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.

- 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

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);

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.

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.
