ec1bd45f4f move some of the debug drawing from btCollisionWorld into btIDebugDraw.h, 
this allows the developer to create better looking debug primitives (sphere, capsule, cylinder, cone and plane)

cb7f4a9728 vectormath requires SSE2, but a single instruction required SSE3, added an #ifdef 
so it compiles on gcc, using both -msse2 and -msse3

ba5012973d Make argument to btDefaultSerializer optional, and use zero by default. This will dynamically allocate data, so there is no need to guess the maximum size anymore. 
Remove some cached data from SoftBodyLinkData, to reduce serialization file size.

6173a30bce Improved BulletSoftBody serialization, added cluster support. Joints and copying data from GPU back to softbody are the main todo. 
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.

032c6bfe2c add initial support for soft body / cloth serialization, and updated SerializeDemo to load soft bodies/cloth. 
Serializes soft body nodes (vertices), links, faces, tetrahedra, materials, anchors with rigid bodies.
Some todo's are serialization of pose, constraints between soft bodies
