ssgLoadAC doesn't generate normals.  That happens in ssgOptimiser (void
OptVertexList::makeNormals()).  This code crashes when it runs on an ASE
model.  What is worse is that ASE models create indexed ssgVtxArrays and
shared verticies imply shared normals.  ssgOptimiser creates face normals
instead of vertex normals.  This means a shared vertex may require two
*different* normals and the indexed ssgVtxArray would have to be rebuilt.
ugh.
