| 1621 |  | Re-fixed bug in octree code that caused it to allocate 8 times as | 
| 1622 |  | much memory as it actually used(!) -- this was pointed out way back | 
| 1623 |  | in 1999 by Erik Reinhard and Erik Jansen, but the fix they gave me | 
| 1624 | < | got lost in the slightly borken release process at the time.  This |
