e260bcd1b2 Added initial Smoothed Particle Hydrodynamics implementation (SPH), for CPU and CUDA. 
This software is contributed under the ZLib license by Rama Hoetzlein, http://www.rchoetzlein.com
We plan to integrate the SPH into the core Bullet library, including interaction with rigid bodies and soft bodies.

f3c3d2f156 + disable perturbation for btConvexPlaneCollisionAlgorithm, it introduces artifacts (additional points cause spheres/cylinders and other curved objects to move) 
+ applied patch to mix double/single precision meshes independent from double/single precision Bullet build
Thanks to Ole for the patch, http://code.google.com/p/bullet/issues/detail?id=213
+ re-enable warming starting in constraint solver, it was disabled by accident

700db838b1 Add 1D and 2D support for Bullet: using rigidbody->angularFactor(const btVector3& factor) and body->setLinearFactor(const btVector3& linearFactor); 
For example, to only allow linear motion in the X-Z plane, and only rotation around Y axis use:
	body->setLinearFactor(btVector3(1,0,1));
	body->setAngularFactor(btVector3(0,1,0));
Fix build issues with CodeBlocks, when generating projectfiles using CMake 2.6:
${OPENGL_glU_LIBRARY} should be ${OPENGL_glu_LIBRARY}
Fix build issue with CodeBlocks, comment out xmlfree in Extras/COLLADA_DOM/src/modules/LIBXMLPlugin/daeLIBXMLPlugin.cpp (will leak memory)

90f96aec27 Introduced btActionInterface. This makes it easier to extend user-defined actions, such as vehicles and characters. 
btRaycastVehicle and btKinematicCharacterController are derived from btActionInterface now.
Some cosmetic cleanup: changed sourceforce/sf.net url to bulletphysics.com.

459c22e7cb Synchronized changes of Bullet, from Blender. 
Added optional flag btSoftBody::appendAnchor(	int node,btRigidBody* body, bool disableCollisionBetweenLinkedBodies=false), to disable collision between soft body and rigid body, when pinned
Added btCollisionObject::setAnisotropicFriction, to scale friction in x,y,z direction.
Added btCollisionObject::setContactProcessingThreshold(float threshold), to avoid collision resolution of contact above a certain distance.
Avoid collisions between static objects (causes the CharacterDemo to assert, when a dynamic object hits character)

5be9f8f301 basic implementation of self-collision for btSoftBody with collision clusters: perform regular soft body versus soft body, but disable collision detection between clusters that are connected/share any node (vertex). 
currently self-collision is always enabled for soft bodies that use clusters collision detectoin. to disable, call 'softbody.m_clusterConnectivity.clear' after 'generateClusters(...) call.

210fe36106 Add backface culling and option to keep unflipped hit normal in case a ray hits a back-facing triangle. 
Usage: set RayResultCallback.m_flags to kF_FilterBackfaces, optionally combined with kF_KeepUnflippedNormal.
Thanks Andy O'Neil for the patch!

Remove the force_inline for some internal constraint solver methods, it makes re-use easier.

7a2a98078a Fixes for broadphase/paircache determinism. 
Revert definition for ATTRIBUTE_ALIGNED16, and try to force sizeof(btSolverConstraint) by using unions with btScalar, for non-btScalar data types.
Use btAssert and not assert.
