I've made some changes to the Scenery handling.  Basically just tidy ups.
The main difference is in tile.[ch]xx where I've changed list<fgFRAGMENT> to
vector<fgFRAGMENT>.  Studying our usage patterns this seems reasonable.
Lists are good if you need to insert/delete elements randomly but we
don't do that.  All access seems to be sequential.  Two additional
benefits are smaller memory usage - each list element requires pointers
to the next and previous elements, and faster access - vector iterators
are smaller and faster than list iterators.  This should also help
Charlie Hotchkiss' problem when compiling with Borland and STLport.

./Lib/Bucket/bucketutils.hxx
  Convenience functions for fgBUCKET.

./Simulator/Scenery/tile.cxx
./Simulator/Scenery/tile.hxx
  Changed fragment list to a vector.
  Added some convenience member functions.

./Simulator/Scenery/tilecache.cxx
./Simulator/Scenery/tilecache.hxx
  use const fgBUCKET& instead of fgBUCKET* where appropriate.

./Simulator/Scenery/tilemgr.cxx
./Simulator/Scenery/tilemgr.hxx
  uses all the new convenience functions.

e33dbca814 Attempting to iron out seg faults and crashes. 
Did some shuffling to fix a initialization order problem between view
position, scenery elevation.

5f1fd50f6a Used a forward declaration of classes fgTILE and fgMATERIAL to eliminate 
the need for "void" pointers and casts.
Quick hack to count the number of scenery polygons that are being drawn.

5ed5107fc1 Ground collision detection optimizations contributed by Norman Vine. 1998-07-16 17:34:24 +00:00

262b2f0607 Added ground collision detection. This involved: 
- saving the entire vertex list for each tile with the tile records.
- saving the face list for each fragment with the fragment records.
- code to intersect the current vertical line with the proper face in
  an efficient manner as possible.
Fixed a bug where the tiles weren't being shifted to "near" (0,0,0)

a60f1d812d Added tile.cxx and tile.hxx. 
Working on rewriting the tile management system so a tile is just a list
fragments, and the fragment record contains the display list for that fragment.
