looptris were referred to as both tris & faces, sometimes polygons were referred to as faces too. Was especially error prone with callbacks that took both a tri and a tri_i arguments. Sometimes tri_i represented a looptri index, other times the corner of the triangle from 0-2. Causing expressions such as: `args->mlooptri[tri].tri[tri_i]` - Rename tri & tri_index -> looptri_i. - Rename faces -> looptris. - Rename face_index/poly_index/poly -> poly_i. - Declare looptri_i at the start of the loop and reuse it, in some cases it was declared with args->prim_indices[i] being used as well.
