Find the final derived mesh tessface for a particle, from its original tessface index. This is slow and can be optimized but only for many lookups.

Parameters
mesh_finalFinal mesh, it may not have the same topology as original mesh.
mesh_originalOriginal mesh, use for accessing MPoly to MFace mapping.
findex_origThe input tessface index.
fwFace weights (position of the particle inside the findex_orig tessface).
poly_nodesMay be NULL, otherwise an array of linked list, one for each final mesh_final polygon, containing all its tessfaces indices.
Returns
The mesh_final tessface index.
