a197c58935 Add #ifdef BT_NO_SIMD_OPERATOR_OVERLOADS before including Bullet headers, to avoid clashes with XNAMath.h 
Fixes Issue 710

9abd0b6029 Sorry for the lack of updates, I am preparing Bullet 3.x initial release and get back to merging Bullet 2.x and Bullet 3.x afterwards. 
fix some crash in btSoftBody, related to running out-of-memory. You can configure the default maximum memory allocation for the signed distance field using worldInfo->m_sparsesdf.Initialize(hash, maxAllocation);
fix 'exploding' btSoftBody, related to very small masses. You can configure maximum displacement per frame using worldInfo->m_maxDisplacement 
avoid some crash in the world importer

e8c2475c95 Added a gCompoundChildShapePairCallback to filter (enable/disable) child shape collisions for a btCompoundShape. 
Thanks to Rich McDaniel for the patch.
See MyCompoundChildShapeCallback in Demos/ConvexDecompositionDemo/ConvexDecompositionDemo.cpp for usage.

1f4f8c7e05 Workaround for sticky convex collisions when using GJK/EPA in combination with very small collision margins. 
In some degenerate cases the contact normal is pointing the wrong direction
so fix it now (until we can deal with all degenerate cases in GJK and EPA)
contact normals need to point from B to A in all cases, so we can simply check if the contact normal really points from B to A
We like to use a dot product of the normal against the difference of the centroids, 
once the centroid is available in the API
until then we use the center of the aabb to approximate the centroid

c4548ec746 Add a helper method that creates a btCompoundShape from a btGimpactMeshShape, for more robust collision detection. 
The idea is to create tetrahedra from each surface triangle, by moving its centroid inwards along the collision normal using depth.
If the centroid hits an internal triangle, it will stop there.

The commit also includes part of the gimpact raycast performance improvement, except for the actual btCollisionWorld part
(that file was out-of-date and needs manual patching)

1d4a5d950d Usually m_contactNormal2 == -m_contactNormal1, but not always, so 
use a separate contactNormal1/contactNormal2 for each body in btSolverConstraint.
