* Updated the BNode system - vastly improved error checking and verify
*
* 12 5/03/99 12:56a 3dsmax
* Knocked MAX_BNODES_PER_ROOM down to 127 after reading the comment about
* a byte count in the portal struct.
*
* 11 5/03/99 12:50a 3dsmax
* Changed MAX_BNODES_PER_ROOM from 100 to 200 for Luke. (MattT)
*
* 10 4/29/99 1:59a Chris
* Added the portal blockage support
*
* 9 4/28/99 5:33a Chris
* Further improved the BNode system. (It actually works inside and
* outside now)
*
* 8 4/27/99 3:01a Chris
* Improving Bnode stuff
*
* 7 4/26/99 11:11a Chris
* Updated Bnode system
*
* 6 4/25/99 9:02p Chris
* Improving the Bnode system
*
* 5 4/18/99 4:35p Matt
* Changed BNode_FreeRoom() to take a room pointer instead of a room
* number, since it was being called for rooms in the scrap buffer, which
* weren't in the room list. Also added code to InitRoom() to init the
* bnode data.
*
* 4 4/18/99 5:39a Chris
* Vastly improved the path node system
*
* 3 4/15/99 5:48p Chris
* Fixed a bug with rendering the BOAPath nodes
