[Cogl] [PATCH 3/3] Add support for per-vertex point sizes

[Neil Roberts]

Actually, one small change that would be good to squash into that patch
would be the following to make it run the vertex transform hook before
running the point size calculation hook. That would make it easier to
make the point size depend on the z position from the vertex transform.
