[Bf-python] How to get inside faces from inside verts?

[joe]

If applying rot/scale works, then it means your script isn't properly
taking the object matrix into account.  To calculate the final
transformed position of a vertex, you have to multiply it with the
object's matrix, like so:

final_vert_co = object.matrix * vert.co
