void btAdjustInternalEdgeContacts ( btManifoldPoint cp,
const btCollisionObjectWrapper colObj0Wrap,
const btCollisionObjectWrapper colObj1Wrap,
int  partId0,
int  index0,
int  normalAdjustFlags 
)

Changes a btManifoldPoint collision normal to the normal from the mesh.

Call the btFixMeshNormal to adjust the collision normal, using the triangle info map (generated using btGenerateInternalEdgeInfo) If this info map is missing, or the triangle is not store in this map, nothing will be done.
