Added base package changes.

Prepairing for 0.7.8 release.

Updated so load/save will work.

Updated config file from Bernie.

More work on the external view panning.

Updates ...

Synced with latest JSBSim.

Nuked the segfault on exit bug everyone was seeing.  The material lib could
have multiple ptrs to individual entries (aliases) but the destructor was
trying to delete every ptr so it would delete already freed memory for aliases.
I implimented a simple ref counting scheme (similar to the plib mechanism) to
track references to material lib entries and only "delete" them when the last
reference is removed.

Most recent changes blew up LaRCsim so we are reverting to a previous
version.

Fix a comment.

We check if the ptr is NULL before deleting it, so set it to NULL after
deleting it.

Just being a tad more careful with setting the ptr to NULL after deleting
it.

Leave view as is when leaving mouse pans view mode.

"Fix a bug" in mouse-pans-external view mode.

MSVC tweaks.

sync with latest JSBSim ...

Updates ...

Begin stubbing in some wrapper code in preparation for runway lighting.

Restructured code a bit to split out the bits that create objects on the
fly.  More work needs to be done.
Added apt_signs.[ch]xx

Removed FGControls.{cpp,h}

Fix a dialog box cancel problem.

- move data structure allocation into constructor (it doesn't belong
  in init)
- free data structures in destructor
- ensure that interpolation tables are allocated before any searching
  is done; otherwise, starting at some locations (such as CYYZ) causes
  a segfault

Shuffled around and restructured the terrain elevation interesection code
to make it usable by the threaded tile loader for placing objects at ground
level at load time.

Attempt to fix a segfault on exit, although I don't think this quite
does it.  We'll have to dig deeper.

Restructured the audio initialization order and don't attempt to continue
loading while intro music is being played.

Fixed a problem with recentering/snaping the view direction to forward so
the panel can come back.

20010710 sync with JSBSim.

- /sim/model/h-rotation renamed to /sim/model/heading-offset-deg
- /sim/model/p-rotation renamed to /sim/model/roll-offset-deg

- modified to take advantage of SGCommandState to cache property nodes
  and other information and avoid expensive lookups in the main loop.

Fixed a typo, tank2 -> tank[1]

Fixed a typo ...

Fix a bug with old-style binary scenery compatibilty where no ground lighting
was generated.

Various cleanups, jettison plib-1.2.0 support, remove a potential memory
leak.

Allow other routines to increment/decrement goal_view_offset while keeping it
in the allowable 0-360 range.

Untweak my button tweak.

Added "/sim/startup/browser-app" as a property.
Added auto coordination to the --help output.

Added "/sim/startup/browser-app" as a property.

Updated to work with current property naming convention.

Use the new plib-1.4.1 sound interface to set a maximum of 6 concurrent
sounds (rather than the default 3).

gcc-3.0 fixes.

Rather than create an SGTime structure and trigger a spurious
"*** NO TIMEZONE" error message, just grab the modified julian date
directly.

Upgraded to handle new default.apt.gz file.

Add a link library needed by Irix.

Add a library needed by Irix.

Oops, typo.

Tweaks.

Updated bug fix to make hopefully more thread safe.

Updates.

Updated to latest revision.

Fixed a bug with warp variable initialization.  fgTie() was nuking out the
initial value.

Fix what looks like it could potentially cause a problem with accessing
previously free'd memory.

Initial revision.

Removed/depricated.

Updated for the latest version of Cygwin.

Updated by Jon.

- modified FGBinding to keep a local copy of the argument property

  handling joystick axes much more efficient
- modified FGBinding to work with the new command state, so that
  commands can save their state (i.e. compiled arguments) from the last
  pass

- implemented FGBinding copy constructor

Makefile.am: distribute irix-hack.sh rather than irix-hack.pl
Thanks: Updated Norman Vine's entry
configure.in: require simgear-0.0.16

Moved DEFAULT_AP_HEADING_LOCK to newauto.hxx
it was defined in both fg_props.cxx and newauto.cxx
