- improvement for edge/face select

  - edges now sample on three locationsm gives more hits
  - own version of glPolygonOffset remains cumbersome... but for select
    now the selection routine gets more offset than draw.

- first attempt to clean drawobject.c and displists
  - generic call for draw object in backbuf for select purposes, cleans up
    a lot in the other calls.
  - also to verify if we can (in future) use this for vertex/edge/face
    select, but the whole drawobject code works against me... this is
    for another refactory (incl. displist) and out of the focus for now

- subsurf.c: now creates new faces in order of original. Not used yet, but is
  handy to recover the original order for selection/paint purposes.
