Option to de/serialize btPersistentContactManifolds and fix lossy conversion during btMultiBody de/serialization of base world transform
(serialize the quaternion, not the converted 3x3 matrix)
There are still several caches not taken into account, and btMultiBody links/constraints are not deserialized yet etc.
See examples\pybullet\examples\saveRestoreState.py for an example.
Add several MSVC optimization flags to cmake.
Bump up VERSION because serialization format changed
Expose btScalar& jointMaxForce, btScalar& jointMaxVelocity to 'getJointInfo2' API, add backwards compatibility to examples\Importers\ImportURDFDemo\URDFImporterInterface::getJointInfo.
pybullet: expose 4 more fields to getJointInfo: jointLowerLimit/jointUpperLimit/jointMaxForce/jointMaxVelocity
fix performance issue in CMD_ACTUAL_STATE_UPDATE_COMPLETED
causing serialization issue in URDF/SDF loading in double-precision mode on Windows 32bit.
(it was fine on Mac/Linux 64bit)
bump serialization version to 2.85, as we change the file format
fix in name clash in makesdna.cpp -> intptr_t is already defined.
So files created by the new double precision serialization of Bullet 2.82 cannot be read by old Bullet versions,
but double precision serialized file generated by older Bullet versions can be read by Bullet 2.82 or newer.
changes are backwards compatible (btBulletWorldImporter can load old .bullet files)
but not forwards compatible (constraints in new .bullet files are ignored/unrecognized by old Bullet SDK)
This commit is for Issue 734. Some more work needs to be done for btGImpactMeshShapeDoubleData and thus btStridingMeshInterfaceDoubleData and btMeshPartDoubleData
fix vehicle demo (heightfield is broken, when using very large scaling factor)
add btConeShape serialization, see Issue 725
add btGearConstraint get/set, see Issue 685 and Issue 671
Updated the Bullet/Demos/SerializeDemo to load .bullet files with the softbody data.
BulletSoftBody should use getWorldTransform and not getInterpolationWorldTransform
Fix btBulletWorldImporter so that it creates a copy of the index/vertex data, this prevents crashes when deleting the .bullet file with triangle meshes.
Serializes soft body nodes (vertices), links, faces, tetrahedra, materials, anchors with rigid bodies.
Some todo's are serialization of pose, constraints between soft bodies
Deal with broken DNA serialization. Bullet 2.76 release revision 2035 - 2046 was broken, and this includes the Maya Dynamica plugin.
Added some workaround to deal with the broken .bullet files, instead of crashing.
improve serialization based on feedback: make it easier to serialize a single object, or single shape, or single bvh.
Modified Bullet/Demos/ConcaveDemo to use btSerializer to serialize the btOptimizedBvh (or optionally the trimesh+bvh)
You can also serialize trimesh without BVH, use:
serializer->setSerializationFlags(BT_SERIALIZE_NO_BVH);// or BT_SERIALIZE_NO_TRIANGLEINFOMAP
So it is different from the in-place method (btQuantizedBvh::serializeInPlace/deserializeInPlace).
It is also possible to serialize/deserialize just the bvh, using the btSerializer (needs some code snippet/helper)

Serialization: remove obsolete autogenerated headers
Minor changes in btSequentialImpulseConstraintSolver: split methods to make it easier to derive from the class and add functionality.
updated serialization structures and header files (for new 'm_name' field, replacing user pointer)
fix issue with btGeneric6DofConstraint::setParam in headerfile
(no motor support or advanced settings yet)
added btStaticPlaneShape serialization
Added toggle in cmake for BenchmarksDemo to enable/disable graphics rendering
Note that BulletFileLoader is has no dependencies on BulletDynamics/BulletCollision.
Also added a custom build step to copy asset (.bullet and .obj file) into the executable folder
Made a few 'char*' 'const char*' to avoid compiler warnings
