 * When creating a MeshShape with triangles that have near identical positions it was possible that the degenerate check decided that a triangle was not degenerate while the triangle in fact would be degenerate after vertex quantization. The simulation would crash when colliding with this triangle.
 * A scaled compound shape with a center of mass of non zero would not apply the correct transform to its sub shapes when colliding with a soft body
 * A soft body without any edges would hang the solver
