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.

9aec3255ef add support for 16bit indices and 3-float vertices (instead of btVector3 which is 4float) in 
in btTriangleMesh container and ColladaConverter.

compile issue with PlatformDefinitions in GDC demo.

eeb78b8d45 free memory for btShapeHulls, keep track of it in GL_ShapeDrawer. 
move btShapeHull and btConvexHull into its own library in Extras/ConvexHull (it allocates memory using mem/delete and refactoring into using btAlignedAlloc/Free takes too much time)
fix heightfield / btOptimizedBvh for quantization, so that raycast can use quantized aabb (clamp up for maxima and down for minima)

work-in-progress (update projectfiles etc)

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.

56c69bc42e - stop threads when exiting demo that uses multi threading 
- improved friction model for parallel solver (align the friction direction with projected velocity, unless the projection is close to zero (only then use 2 arbitrary axis orthogonal to contact normal)

830c096e10 added a cellDmaLargeGetReadOnly/cellDmaGetReadOnly, which avoid memcpy on non-SPU platforms. 
enabled it for triangle mesh aabb DMA transfers. Todo: check if it is worth also modifying other parts of the code to avoid the memcpy into the 256kb Task memory.
