- bug fix #694

when using linked-duplicated mesh, with subsurf and tfaces (UV texture)
  the render crashed.
  Found out the renderloop makes a new displaylist for each Mesh, also when
  it is linked multiple times. That way pointers to previous created elements
  in displaylists become invalid. Crash!
  Result now it even renders faster for linked-duplis. :)
