+ more consistent 'setLocalScaling' for the btCompoundShape. Full non-uniform scaling is not supported when child shapes have a rotation. If any child shapes have rotation, the best you can do is either uniform scaling, or 'baking' the non-uniform scaling into the child geometry (vertices of a convex hull for example)

+ fixed an issue with BulletWorldImporter, btBoxShape implicitShapeDimensions already includes local scaling.
