Calculates paths ready for drawing/rendering

• Useful for making use of opengl vertex arrays for super fast strand drawing.
• Makes child strands possible and creates them too into the cache.
• Cached path data is also used to determine cut position for the editmode tool.

	)

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_final	Final mesh, it may not have the same topology as original mesh.
mesh_original	Original mesh, use for accessing MPoly to MFace mapping.
findex_orig	The input tessface index.
fw	Face weights (position of the particle inside the findex_orig tessface).
poly_nodes	May 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.
