-// modifications to obj loader to handle tri fans.
-//
-// Revision 1.13 1999/03/27 05:36:03 curt
-// Alas, I have made non-backwardsly compatible changes to the scenery file
-// format. Thus I have had to make the corresponding changes here in the
-// file loader.
-// Things that do not correspond the the .obj format are placed in comments.
-//
-// Revision 1.12 1999/03/02 01:03:25 curt

-// Added initial support for native SGI compilers.
-//
-// Revision 1.10 1998/11/06 21:18:18 curt

-// builds with no messages at all (and no performance impact) by using
-// the -DFG_NDEBUG flag.
-//

-// duplicating work.)
-// Tweaked fgTileMgrRender() do not calc tile matrix unless necessary.
-// removed some unneeded stuff from fgTileMgrCurElev()
-//
-// Revision 1.3 1998/09/03 21:27:03 curt
-// Fixed a serious bug caused by not-quite-correct comment/white space eating
-// which resulted in mismatched glBegin() glEnd() pairs, incorrect display lists,
-// and ugly display artifacts.
-//
-// Revision 1.2 1998/09/01 19:03:09 curt
-// Changes contributed by Bernie Bright <bbright@c031.aone.net.au>
-// - The new classes in libmisc.tgz define a stream interface into zlib.
-// I've put these in a new directory, Lib/Misc. Feel free to rename it
-// to something more appropriate. However you'll have to change the
-// include directives in all the other files. Additionally you'll have
-// add the library to Lib/Makefile.am and Simulator/Main/Makefile.am.
-//
-// The StopWatch class in Lib/Misc requires a HAVE_GETRUSAGE autoconf
-// test so I've included the required changes in config.tgz.
-//
-// There are a fair few changes to Simulator/Objects as I've moved
-// things around. Loading tiles is quicker but thats not where the delay
-// is. Tile loading takes a few tenths of a second per file on a P200
-// but it seems to be the post-processing that leads to a noticeable
-// blip in framerate. I suppose its time to start profiling to see where
-// the delays are.
-//
-// I've included a brief description of each archives contents.
-//
-// Lib/Misc/
-// zfstream.cxx
-// zfstream.hxx
-// C++ stream interface into zlib.
-// Taken from zlib-1.1.3/contrib/iostream/.
-// Minor mods for STL compatibility.
-// There's no copyright associated with these so I assume they're
-// covered by zlib's.
-//
-// fgstream.cxx
-// fgstream.hxx
-// FlightGear input stream using gz_ifstream. Tries to open the
-// given filename. If that fails then filename is examined and a
-// ".gz" suffix is removed or appended and that file is opened.
-//
-// stopwatch.hxx
-// A simple timer for benchmarking. Not used in production code.
-// Taken from the Blitz++ project. Covered by GPL.
-//
-// strutils.cxx
-// strutils.hxx
-// Some simple string manipulation routines.
-//
-// Simulator/Airports/
-// Load airports database using fgstream.
-// Changed fgAIRPORTS to use set<> instead of map<>.
-// Added bool fgAIRPORTS::search() as a neater way doing the lookup.
-// Returns true if found.
-//
-// Simulator/Astro/
-// Modified fgStarsInit() to load stars database using fgstream.
-//
-// Simulator/Objects/
-// Modified fgObjLoad() to use fgstream.
-// Modified fgMATERIAL_MGR::load_lib() to use fgstream.
-// Many changes to fgMATERIAL.

-// Wrote access functions for current fgOPTIONS.
-//
-// Revision 1.18 1998/07/12 03:18:27 curt
-// Added ground collision detection. This involved:

-// fragment.
-//
-// Revision 1.5 1998/05/20 20:53:53 curt
-// Moved global ref point and radius (bounding sphere info, and offset) to
-// data file rather than calculating it on the fly.
-// Fixed polygon winding problem in scenery generation stage rather than
-// compensating for it on the fly.

-//
-// Revision 1.4 1998/05/16 13:09:57 curt
-// Beginning to add support for view frustum culling.

-// Minor transformation adjustments to try to keep scenery tiles closer to
-// (0, 0, 0) GLfloats run out of precision at the distances we need to model
-// the earth, but we can do a bunch of pre-transformations using double math

-// precision problems.
-//
-// Revision 1.31 1998/04/25 15:09:57 curt
