The functions with cullmask are less used than those without. Functions for 1
and 2 vertices are less used than the 3 and 4 cases. Probably the top few are:
cliptest-points-4
transform_points3_general_raw
transform_points3_3d_no_rot_raw
I'd also add
transform_points3_3d_raw
and have a look at the ones used by the fx/mga fast paths in vertices.c. These
are the ones used by q3.
