[Bf-committers] derived mesh in modifier stack

As far as i found out, a DerivedMesh is created as soon as some modifier
needs to construct its own geometry. There are the utility functions
get_dm() and get_cddm() in MOD_util. What is their purpose? I looked at
what they are doing and it looked like get_cddm() would ensure a
DerivedMesh is created. But somehow it does not update the vertices and
How im supposed to access the vertex normals that would exist after the
last modifier worked on them, before my own modifier, if it is just a
deform modifier, that does not deliver a new DerivedMesh?
In other words: Can i update the DerivedMesh passed to deformVerts()? Or
is there a better way to access the current normal data? Vertices seam
not to be updated after get_dm() or get_cddm().
Best wishes Tobias Oelgarte
