Subsurf: Subdivide polygons to the same resolution

Previously it was ptex faces which were subdividing to the same
resolution. This was looking like more details for non-quad faces,
but was also causing discontinuity in the edge where quad touches
non-quad polygon.

Now ptex faces which are coming from non-quad faces are subdivided
at a half of resolution, matching old behavior and solving
discontinuity problem.
