This display list was only used for texture space calculation, and even there this display list was only used for bounding box calculation. Since we already do have bounding box in a curve datablock there's no reason to duplicate non-modified display list just to calculate bounding box later, let's just calculate bounding box at the first point. This makes code a little be more thread-safe but curves are still not safe for threads at all because of bevel list and path. That would be solved later. -- svn merge -r57939:57940 ^/branches/soc-2013-depsgraph_mt
