Disable libxml LIBXML_MODULE_EXTENSION
Fixed include path in btConeTwistConstraint (it should be relative to src folder, not using ../../ )
Thanks to ejtttje, http://code.google.com/p/bullet/issues/detail?id=129
Add CMake install support for libbulletmath,libbulletcollision,libbulletdynamics,libbulletsoftbody,and toplevel include files
Options to enable/disable BUILD_DEMOS and BUILD_ETRAS
Fixed compile issue in BulletMultiThreaded
Fixed double-precision issues with btMatrix3x3::getEulerZYX
to build, go to Bullet/src/ibm_sdk and run make
then, go to Bullet/src/BulletMultiThreaded/ibm_sdk
make -f Makefile.original spu
make -f Makefile.original ppu
btQuantizedBvh has a version number, memory layout might be different now (due to aligned btVector3)
reorganized some data members of some classes, to reduce memory footprint
BulletMultiThreaded/NarrowPhaseCollision makes use of this boxBoxDistance.
Cache some values in src/BulletMultiThreaded/SpuContactManifoldCollisionAlgorithm.cpp, to avoid DMA transfers
2) Added btConvexSeparatingDistanceUtil: this allows caching of separating distance/vector as early-out to avoid convex-convex collision detection.
btConvexSeparatingDistanceUtil is used in src/BulletCollision/CollisionDispatch/btConvexConvexAlgorithm.cpp and can be controlled by btDispatcherInfo.m_useConvexConservativeDistanceUtil/m_convexConservativeDistanceThreshold
3) Use BulletMultiThreaded/vectormath/scalar/cpp/vectormath/scalar/cpp/vectormath_aos.h as fallback for non-PlayStation 3 Cell SPU/PPU platforms (used by boxBoxDistance).
Note there are other implementations in Extras/vectormath folder, that are potentially faster for IBM Cell SDK 3.0 SPU (libspe2)
