	  Profiling startup with the new effects code exposed some
	  performance gotchas. The objective is to reduce allocation of
	  std::string temporaries, especially when looking up node path
	  names. Also, I changed some paths to initialize strings with
	  strings instead of char *; this causes less allocation, at least
	  with glibc. Also, eliminate the old version of find_node and its
	  helper functions by writing the template version of find_node_aux
	  to handle an explicit index parameter.

	  Also, add const char[] as an internal property type

	  This doesn't actually add a new type to the property system, but
	  allows using character arrays as arguments to certain templates.

2009-10-18 11:34  ehofman

	* simgear/sound/: sample_group.cxx, sample_group.hxx,

	  Initialization was done much earlier than expected resulting in

	  fix alutInit counter remove left over static declaration fro

	  unfortunately at this time orientation seems to be from straight
	  behind which means that sounds that have outer-gain set to 0.0
	  will not be heard yet.

	* simgear/sound/: sample_group.cxx, sample_group.hxx,
	  soundmgr_openal.cxx, soundmgr_openal.hxx: OpenAL buffer
	  management; add a buffer cache to prevent loading the same sample
	  in memory twice. Especially useful to save memory for
	  multi-aircraft configurations and (later) for AI models.

	* simgear/sound/: sample_group.cxx, sample_group.hxx,

2009-10-07 09:31  ehofman

	* simgear/sound/soundmgr_openal.cxx: alut pre-1.0 doesn't support

2009-10-06 22:05  jmt

	* simgear/screen/: screen-dump.cxx, screen-dump.hxx: Update the

	* simgear/sound/: sample_group.cxx, sample_group.hxx,

	  is not aliased).

	* simgear/timing/: sg_time.cxx, sg_time.hxx:  For the first time

	   pun intended) that I'm touching the time library.

	   Brian Schack reported that the traffic scheduler messes up the
	  timestamps
	   of the atlas network output. As it turns out, the c library
	  functions
	   asctime, and gmtime use a static copy of the tm struct to do the
	  internal
	   formatting. Our linux port of the SGTime class, incidentally,
	  also stored
	   it's master time stamp in this very same struct. Thus,
	  formatting an
	   arbitrary time value, would have the unwanted side effect of
	  time travel.
	   Usually, this would go unnoticed, because the actual time
	  parameters would
	   be updated before any damage could be done. But unwanted side
	  effects, as
	   in Brian's example could occur.

	   On the MSVC port this appears to not have been a problem. Since
	  that port
	   used a copy of the tm struct to store it's master time stamps.
	  Since the
	   MSVC code also compiles cleanly on linux, it seems to be the way
	  to go to
	   use that approach. In addition, it also removes some conditional
	  compile
	   directives.

	   I've only run a short test, but didn't see any undesirable side
	  effects.

	  Tim's improvements - Changes the transparency of the clouds.
	  Previously, the clouds were transparent at 0m distance, opaque at
	  200m, then gradually more transparent to the fog limits. This
	  meant they were generally quite transparent. Now, they are opaque
	  from 200m to 15km, then become transparent at 20km. A side effect
	  of this is that the current textures could probably benefit from
	  being made slightly transparent to improve the blending of the
	  sprites against each other.

	  This provides the following enhancements & bug fixes - Fix the
	  chequer-board bug.  - Add proper cloud coverage function - so
	  scattered clouds are now truly scattered.  - Add real-time
	  control for visibility range.  - Use a limited set of clouds
	  rather than generating a completely new Geode for each cloud.
	  This saves sorting and display time.	- Add controls to Rendering
	  dialog to allow fine-tuning of the number of sprites, cloud
	  visibility and the number of different types of cloud.  - Add
	  some variance to the sort back-off to avoid all clouds being
	  sorted at the same time.  - Pack attributes into vectors for
	  performance - Re-order the cloud type determination code so that
	  if a cloud layer could either be stratus or cumulus, cumulus is
	  used.  - Lowered the cloud level in the standard cloud
	  configuration slightly so a cumulus layer is generated rather
	  than stratus.

	  These last two mean that you should see some 3D cumuli if
	  disabling real weather fetch.

	  Well, the cause was a bug in my code, but it didn't expose itself
	  until we moved to multiple cameras. The attached patch fixes the
	  problem.

	  I've also put in a new heuristic to improve the frame-rate.
	  Clouds that are already sorted are likely to still be sorted in
	  subsequent frames. Therefore I've put in a back-off mechanism for
	  the bubble-sort pass. This should mean that if you stay
	  completely stationary, once the clouds become sorted they will
	  eventually only perform a bubble sort pass every 128 frames.

	* simgear/scene/sky/CloudShaderGeometry.cxx: Manuel Massing:

	  Attached is a small fix for the sorting in

	  the osg idiosyncracy to store transposed matrices...so the
	  intuitive

		 osg::Vec4f p = vm *
	  osg::Vec4f(_cloudsprites[i]->position.osg(), 1.0f);

	  needs to be replaced with...

		 osg::Vec4f p =
	  vm.preMult(osg::Vec4f(_cloudsprites[i]->position.osg(), 1.0f);

	  The patch also optimizes the distance calculation - it evaluates
	  the distances in model space instead of eye space, which reduces
	  computation to a dot- product instead of a matrix multiplication.

	  CloudShaderGeometry.hxx, cloudfield.cxx, cloudfield.hxx,
	  newcloud.cxx, newcloud.hxx, sky.cxx, sky.hxx: Stuart Buchanan :
	  It fixes the following issues (to a greater or lesser extent): 1)
	  Performance. Quad trees used to improve culling, and the sprites
	  are placed on the surface of a sphere rather than randomly
	  throughout the cloud, requiring fewer textures. This saves about
	  5-10fps on my machine.  2) Disabled 3D clouds have no performance
	  impact. Previously they were still in the scenegraph. Now they
	  are removed.	3) Clouds are now loaded on start-up, and don't
	  require the scenario to be changed, they also work with METAR.
	  4) The cloud field is shifted as you travel. There's a small bug
	  in that the clouds "jump" as you reach the edge of the field.  5)
	  Iterative sorting of sprites. This doesn't appear to solve the
	  alpha blending problem completely, but may help a bit.

	  gc.c, hash.c, iolib.c, lex.c, lib.c, misc.c, naref.h, nasal.h,
	  parse.c, parse.h, string.c, threadlib.c, utf8lib.c, vector.c:
	  Sync with Nasal upstream (Melchior already had a chance to test
	  this, so hopefully not too much breaks).  New syntax features:

	  1. Call-by-name function arguments.  You can specify a hash
	  literal in place of ordered function arguments, and it will
	  become the local variable namespace for the called function,
	  making functions with many arguments more readable.  Ex:

	     view_manager.lookat(heading:180, pitch:20, roll:0, x:X0, y:Y0,
	  z:Z0,
				 time:now, fov:55);

	  Declared arguments are checked and defaulted as would be
	  expected: it's an error if you fail to pass a value for an
	  undefaulted argument, missing default arguments get assigned, and
	  any rest parameter (e.g. "func(a,b=2,rest...){}") will be
	  assigned with an empty vector.

	  2. Vector slicing.  Vectors (lists) can now be created from
	  others using an ordered list of indexes and ranges.  For example:

	     var v1 = ["a","b","c","d","e"]

	     var v2 = v1[3,2];	 # == ["d","c"];
	     var v3 = v1[1:3];	 # i.e. range from 1 to 3: ["b","c","d"];
	     var v4 = v1[1:];	 # no value means "to the end":
	  ["b","c","d","e"]
	     var i = 2;
	     var v5 = v1[i];	 # runtime expressions are fine: ["c"]
	     var v6 = v1[-2,-1]; # negative indexes are relative to end:
	  ["d","e"]

	  The range values can be computed at runtime (e.g. i=1;
	  v5=v1[i:]).  Negative indices work the same way the do with the
	  vector functions (-1 is the last element, -2 is 2nd to last,
	  etc...).

	  3. Multi-assignment expressions.  You can assign more than one
	  variable (or lvalue) at a time by putting them in a parenthesized
	  list:

	     (var a, var b) = (1, 2);
	     var (a, b) = (1, 2);		# Shorthand for (var a, var
	  b)
	     (var a, v[0], obj.field) = (1,2,3) # Any assignable lvalue
	  works

	     var color = [1, 1, 0.5];
	     var (r, g, b) = color;  # works with runtime vectors too

	  paging patch from Till Busch

	  Comments from Till: I started the project at the end of february
	  with a simple idea: move all 3d-model loading to the
	  DatabasePager-thread. my first attempts looked promising, though
	  they were a little too optimistic (or naive?). the patch has
	  evolved a lot since.

	  currently it does the following things: 1. revive SGModelLib,
	  move functions for xml-model-loading there

	  2. replace all calls to sgLoad3dModel with calls to either
	  SGModelLib::loadModel() or SGModelLib::loadPagedModel() almost
	  all models will be loaded by the DatabasePager. the few
	  exceptions are: your own plane, shared models in scenery, random
	  objects, AIBallistic models.

	  3. simplify mode-loading functions (avoid passing around fg_root)

	  4. avoid supurious MatrixTransform nodes in loaded models

	  5. fix some memory leaks

	  The cause seems to be the condition in SGMaterialAnimation.cxx
	  l.277 ignoring any texture update by the UpdateCallback (only
	  there <texture-prop> is looked at)  without an already existing
	  stateSet.  That in turn will not be created with a <texture-prop>

	  Unless I overlooked some compelling reason contradicting, I'd

	  animation.cxx (PRE_OSG_PLIB_20061029) and is imho the more

	  announced that it'll get     fixed.) For removal try	   $ cd
	  simgear/sound     $ cvs diff -rAFTER_OPENAL_DOPPLER_WORKAROUND
	  -rBEFORE_OPENAL_DOPPLER_WORKAROUND|patch

	* simgear/sound/: sample_openal.cxx, sample_openal.hxx,
	  soundmgr_openal.cxx, xmlsound.cxx: Maik JUSTUS: Doppler fixes
	  (add option to turn off Doppler for sounds that
	  shouldn't be affected -- marker beep, ATIS messages, etc.)

	  mf: this is the first part of the original patch. It is supposed
	  to contain	 fixes that are not caused by OpenAL bugs, and thus
	  aren't meant to be	 reverted later. The second part will
	  contain a temprary workaround for	OpenAL bugs. Unfortunately,
	  I had to do the split myself as the contributor     refused to do
	  it.

	* simgear/props/: props.cxx: - close loophole through which one
	  could sneak in illegal property names   containing slashes,
	  colons and all sorts of evil characters. In Nasal   this could be
	  done via props.globals.getChild("1!@#$//[]{}", 0, 1).setValue(0);
	  The cause is that getChild() hands the given name directly over
	  to an   alternative SGPropertyNode ("convenience") constructor
	  which sets the   name without any checks.  - unify exception
	  messages: first character is lower case

2007-07-12 12:43  mfranz

	* simgear/scene/model/shadanim.cxx: allocate W*H*4 bytes (rather
	  than W*H*3), as it turned out that glGetTexImage() returns that
	  much for the default red/white chequer texture, which is used
	  when the requested texture couldn't be found.  This could be a
	  bug in the implementation (nvidia/100.14.11/Linux x86) or be
	  normal for compressed textures
	  (GL_COMPRESSED_RGBA_S3TC_DXT5_EXT).  The OSG developers aren't
	  sure about their sizes either (see comment in src/osg/Image.cpp,
	  revision 7067: computePixelSizeInBits()).

	  for the 2x2 RGB red/white chequer texture:

		0 1 2 3 4 5 6 7 8 9 a b c d e f
	    IN: ff0000ffffffffffffff0000	  (see
	  src/ssg/ssgLoadTexture)
	   OUT: f70000ffffff....fffffff70000....

	  where the positions marked with a dot remained untouched.

	* simgear/sound/: sample_openal.cxx, sample_openal.hxx,

	  JUSTUS:

	  "[...] switches of the Doppler calculation of OpenAL and adds a
	  own Doppler calculation."

	  mf: necessary because OpenAL Doppler on Windows is broken, which
	  the	  openal developers acknowledge. The source revisions
	  before and after     the patch was applied are tagged with
	  BEFORE_OPENAL_WORKAROUND and	   AFTER_OPENAL_WORKAROUND, so that
	  one can easier find and remove     the changes if required
	  (which is quite unlikely. :-)

2007-07-02 17:42  mfranz

	* simgear/timing/: lowleveltime.cxx, timezone.cxx: replace exit()

	  interdependencies between sg libs are generally unwelcome, but
	  sg_exception is a rather basic part, and it's already used by
	  xml, props, scene, sound and, of course, structure. Since props
	  and xml are core libs, we can assume that sg_exceptions are
	  available.  (OK'ed by Curt)

2007-03-30 18:42  andy

	* simgear/nasal/mathlib.c: Melchior points out that NaN/Inf
	  behavior is not platform-independent.  So toss a runtime error
	  ("floating point error") when any of the math library functions
	  produce a non-finite value.  Note that these are not the only
	  locations that can do that (simply dividing by zero will produce
	  an Inf), but it's still proper behavior.

	* simgear/nasal/: Makefile.am, bitslib.c, code.c, code.h,

	  thread-posix.c, thread-win32.c, threadlib.c, utf8lib.c, vector.c:
	  sync with trunk

	* simgear/nasal/: Makefile.am, bitslib.c, code.c, code.h,
	  codegen.c, data.h, gc.c, hash.c, iolib.c, lex.c, lib.c,
	  mathlib.c, misc.c, naref.h, nasal.h, parse.c, parse.h, string.c,
	  thread-posix.c, thread-win32.c, threadlib.c, utf8lib.c, vector.c:
	  Sync with Nasal CVS (soon to become Nasal 1.1).  Notable new
	  features:

	  Nasal now supports calls to "subcontexts" and errors can be
	  thrown across them, leading to complete stack traces when call()
	  is used, instead of the truncated ones we now see.

	  Vectors can now be concatenated using the ~ operator that used to
	  work only for strings.

	  Better runtime error messages in general due to a fancier
	  naRuntimeError() implementation

	  A big data size shrink on 64 bit systems; the size of a naRef
	  dropped by a factor of two.

	  "Braceless code blocks" have been added to the parser, so you can
	  write expressions like "if(a) b();" just like in C.  Note that
	  there's still a parser bug in there that fails when you nest a
	  braced block within a braceless one.

	  Character constants that appear in Nasal source code can now be
	  literal multibyte UTF8 characters (this was always supported for
	  string literals, but character constants were forced to be a
	  single byte).

	  New modules: "bits", "thread", "utf8" and (gulp...) "io".  The
	  bits library might be useful to FlightGear, the utf8 one probably
	  not as Plib does not support wide character text rendering.  The
	  thread library will work fine for spawning threads to do Nasal
	  stuff, but obviously contact with the rest of FlightGear must be
	  hand-synchronized as FlightGear isn't threadsafe.  The io library
	  is no doubt the most useful, as it exposes all the basic stdio.h
	  facilities; it's also frighteningly dangerous when combined with
	  networked code...

	* simgear/nasal/: code.c, code.h, codegen.c, gc.c, lib.c, vector.c:
	  Been hacking at Nasal recently:

	  Fix bug with break/continue inside of a foreach or forindex:
	  Don't pop the vector/index inside OP_EACH, do it at the end of
	  the loop.

	  In the process, discovered and fixed a scary corruption issue
	  with continue; it never really worked right, although simple
	  usage was likely to get away without crashing.  Both the
	  continue's OP_BREAK and the cleanup code at the end of a loop
	  would pop the "mark" stack, leading to an underflow.	Introduced
	  an OP_CONTINUE which adjusts stack but doesn't change markTop

	  Re-inline the PUSH macro.  This thing is called all over the
	  place from the inner loop.  If the problem is intra-expression
	  side effects, then just use another expression in the macro.

	  Return an empty vector when requesting zero-length subvec, not
	  nil

	  Have call() return the call stack in the error vector; see docs
	  on plausible.org/nasal or ask Andy about this feature.

	  Default closure()'s level argument to zero, not nil

	  Add an optional "file name" argument to compile()

	* simgear/scene/tgdb/: apt_signs.cxx, apt_signs.hxx: rename
	  OBJECT_TAXI_SIGN to OBJECT_SIGN. This isn't about taxi signs any

	* simgear/nasal/lib.c: Oops, implement the previously-mentioned fix
	  without breaking support for omitting a length argument to mean
	  "the rest of the vector".

2006-03-21 23:22  andy

	* simgear/nasal/lib.c: The original code (rather oddly) interprets
	  a length of zero in subvec() to mean "the whole vector".
	  Melchior showed a use case (removal of the first element from a
	  vector) where getting a zero-length subvector is actually
	  desired.  And since I can't come up with a good reason for why
	  the "feature" was there in the first place, out it goes...

2006-03-21 22:57  andy

	* simgear/nasal/lib.c: Melchior discovered that cmp() was just
	  wrong, failing to actually inspect the string pointers.  It also
	  failed to properly sort strings where one is a prefix of the
	  other.  It looks to me like I just never finished this, and it
	  ended up in CVS because it just happened to compile...

	* simgear/nasal/iolib.c: The handle gets nulled out if the user has
	  closed the file; don't pass that null to fclose() in a garbage
	  collection destructor too...

2006-03-15 20:42  andy

	* simgear/nasal/: Makefile.am, bitslib.c, iolib.c: Fix broken
	  checkin in iolib.c.  Also add the 'bits' library, which has a
	  buf() function needed to make convenient use of io.read().

2006-03-15 20:35  andy

	* simgear/nasal/iolib.c: Melchior found the first bug -- report EOF
	  as nil in readln().

2006-03-15 19:09  andy

	* simgear/nasal/: Makefile.am, iolib.c, iolib.h: Add the Nasal I/O

	  (reviewed by Fred, who also fixed *my* bugs :-)

2006-03-12 19:56  mfranz

	* simgear/scene/model/model.cxx: Better use a node that is very

	  Add MAC OS X Render Texture support:

	  Most texture modes seem to work on my Powerbook, but I don't have
	  a wide array of machines to test it on otherwise.

	  If you have problems, please let me know and I'll see if I can
	  help track down the source of the bug.  I'd love to keep working
	  on it if time permits (I use RenderTexture in a few other
	  projects), so I'll keep you informed if there are any changes
	  that I make for the better.

2006-03-09 10:03  mfranz

	* simgear/scene/: material/matmodel.cxx, model/model.cxx,
	  model/model.hxx, model/modellib.cxx, model/modellib.hxx:
	  model.[ch]xx:   add abstract class SGModelData. If a pointer to
	  such a class is handed over	to sgLoad3DModel, then its
	  modelLoaded() method is called with path, property   node and
	  branch. And then it's added to the scene graph so that it's
	  destroyed when the model branch is removed from the graph.

	  modellib.[ch]xx:   only cache objects when asked to. This is the
	  case for OBJECT_SHARED   and random objects (like before), but no
	  longer for OBJECT_STATIC.    These are now removed from the graph
	  when they are "out of sight". This	prevents accumulation of
	  static models, and makes destroying model data    possible (e.g.
	  removing Nasal modules)

	  matmodel.cxx:   set cache flag for random objects (same behavior
	  as before)

	  This patch makes use of the vectors now available in simgear with
	  that past patch. And using that it simplyfies the carrier code
	  somehow.

	  - Small additional factory's to the quaternion code are done in
	  the simgear	part. Also more explicit unit names in the factory
	  functions.  - The flightgear part makes use of them and
	  simplyfies some computations	 especially in the carrier code.  -
	  The data part fixes the coordinate frames I used for the park
	  positions in	 the carrier to match the usual ones. I believed
	  that I had done so, but it   was definitly different. Also there
	  are more parking positions avaliable now.

	  sg_geodesy.cxx, sg_geodesy.hxx: Mathias Fröhlich:

	  The patch adds a vector lib I have put together during the last
	  time, it is just handy and interfaces well with s(s)g*. Together
	  with some small modifications this will later also interface well
	  with OpenSceneGraphs vectors/matrices. Using this vector kernel
	  is targeted to have a handy matrix/vector lib available and to
	  provide a scenegraph independent vector type for use with a small
	  scenegraph wrapper aimed for a smooth transition to
	  openscenegraph.

	  That vector code also includes an improoved geodetic conversion
	  routine I have found some time ago published in the 'journal of
	  geodesy' which avoids iterative computations for that purpose.

	  Also the geodetic position class is more typesafe and unitsafe
	  than the Point3D currently is.

	  That part is relatively old and in use in my local trees for
	  several months now.

	* SimGear.dsp, SimGear.dsw, am2dsp.cfg, simgear/constants.h,
	  simgear/math/fastmath.hxx, simgear/nasal/mathlib.c: Olaf Flebbe:

	  This patch makesFlightGear at least compile on MSVC. I hope I
	  have removed reference of my other local changes. DSP and DSW
	  files are included for reference. They have been reconstructed
	  with am2dsp.pl. I had to introduce a change to am2dsp because of
	  the need of filenames with embedded spaces. (Yuck)

	  The major direction is to remove clutter like the
	  _USE_MATH_DEFINES and have it on the compiler command line sice
	  there is no central include file. You will have to put it on the
	  command line for your locale Project files, if it not there,
	  already. I added the _CRT_SECURE_NO_DEPRECATE define for 2005,
	  since it does no harm to other VC version.

	  Third Party Libs like plib, OpenALSDK, freeglut, pthreads-win32,
	  zlib are unpacked as is side by side. Only change put the
	  includes of OpenAL into include/AL rather directly into include.

2006-01-30 11:56  ehofman

	* simgear/props/: props.cxx, props.hxx: Melchior FRANZ:

	  add optional arg to SGPropertyNode::addChangeListener that
	  triggers the listener function call initially. This is useful for
	  cases where a freshly installed listener wants to treat the
	  current property value as changed from 'unknown' to the actual
	  value right away.

	  Examples can be found in the Nasal incarnation setlistener(),
	  where we have for example this (in $FG_ROOT/Nasal/gui.nas):

	    INIT = func {
		...
		setlistener("/sim/rendering/fps-display", fpsDisplay);
		if (getprop("/sim/rendering/fps-display")) {
		    fgcommand("dialog-show", props.Node.new({"dialog-name":
	  "fps"}));
		}
	    }

	  That is: we first attach a listener that cares for changes to the
	  FPS display switch, but then we have to manually open the dialog
	  initially.  That's a duplication of code and could be as simple
	  as this (INIT part only):

	    INIT = func {
		...
		setlistener("/sim/rendering/fps-display", fpsDisplay, 1);
	    }

	  That is: the optional third arg makes fpsDisplay be called
	  initially, and then again with every write action. My first
	  solution was in the Nasal code only, but Andy (rightfully) says
	  that this should rather be in sg.

	* simgear/props/: props.cxx, props.hxx: Melchior FRANZ:

	  The attached patch makes remove_child() available as
	  removeChild(pos, keep).  That's consistent with getChild. Only
	  renamed remove_child to removeChild and added a check for
	  validity of the pos argument.

	  removeChildren() will be used in input.cxx, and a lot in the
	  upcoming dynamic new_gui dialogs, which are aiming at replacing
	  the hard-coded dialogs. I'll discuss them on the list once the
	  infrastructure is in place. (The <hide> gui property was one part
	  of it.)

	  Correct the bug in the translate animation where the offset was
	  part of the multiplication. It now behaves like all other
	  animations: out = (prop * factor) + offset

	  I feel strongly that the existing is wrong and must be corrected
	  - it is non-op if the offset is zero as I have found to my cost!
	  It is just a typo I expect.

	  The diff also provides non-op default values for the scale
	  animation.

	  I've also included Harald's latest eye-candy animation which
	  allows us to have a very smart heat-haze for exhausts. They have
	  been tested by me and others on Linux and Cygwin. You might like

	  not all systems are capable of running fgfs.	Beyond that,
	  multiple threading bugs were fixed, and the naCall() API changed
	  slightly to support named function arguments.

	* simgear/screen/: RenderTexture.cpp, extensions.cxx: Mathias
	  Fröhlich:

	  just a few split out patches from my zoo of local work ...

	  The patch to simgear-glxproc.diff changes dlopen to not open a
	  specific library.  If it is used with a NULL argument, we just
	  get a handle to the current running binary including all loaded
	  libraries. This has the advantage that we do not rely on the name
	  of libGL on the specific platform.  Also a user can link with his
	  own different named libGL or with a static libGL.a

	  Then the render texture again ...

	  glxQueryVersion turns out to return the  minimum of the client
	  libraries glx version and the servers glx version. *All* Xorg
	  servers return 1.2 here.  So we never get the glxPBuffer
	  functions  which are the only ones working with ati's drivers ...
	   Reverted back to checking the required functions and just use
	  them if they are there. Still prefering the glx standard variants
	  since they work on ati's drivers ...

	* simgear/scene/model/: animation.cxx, animation.hxx, model.cxx,
	  shadowvolume.cxx, shadowvolume.hxx: Harald JOHSEN:

	  Changes =======

	  - shadowvolume.cxx, renderer.cxx :   - reduced the polygon offset
	  a bit to eliminate some artifact ;   - changed again the cleanup
	  code for objects inside a tile because it could crash on rare
	  occasion ;   - the culling of shadow casters has been rewritten
	  to traverse the scene graph, it should be	a bit faster when
	  there is a lot of objects ;	- the range selector was not
	  correctly handled, sometimes the wrong LOD was casting shadows.
	   - added the option to display aircraft's transparent objects
	  after the shadows, this will	    reduce the problem of shadows
	  being hidden by the transparent object (propeller disk,
	  rotor, etc). A side effect is that aircraft's transparent objects
	  won't receive shadows      anymore. This is usually a good thing
	  except when the aircraft use a 'transparent'	    texture where
	  it should not. A transparent texture in the plib context is a
	  texture      with an alpha channel or a material with alpha <=
	  0.99.

	  - model.cxx, animation.cxx, shadowvolume.cxx :   - added an
	  optional <condition> under the <noshadow> animation

	  - tower.cxx	- correct a rare bug where all occurences of the
	  aircraft are not deleted from the   departure list causing a
	  crash in FGTower::CheckDepartureList function.

2005-07-13 14:00  ehofman

	* simgear/screen/: RenderTexture.cpp, RenderTexture.h,

	* simgear/scene/model/: shadowvolume.cxx, shadowvolume.hxx: Harald
	  JOHNSEN:

	  Melchior has found another bug, I tried to skip some computation
	  for a few frames but that introduced some bad rendering bug with
	  the aircraft moving parts.  I corrected that and reduced a bit
	  the cpu usage for ground objects.

2005-07-05 20:53  ehofman

	* simgear/scene/model/shadowvolume.cxx: Another update, the
	  previous one could crash if you leave the surrounding tiles (try
	  Set aircraft in air and choose a distant airport).

2005-07-05 20:00  ehofman

	* simgear/scene/model/shadowvolume.cxx: Somehow gcc allows function

	  scene/model/shadowvolume.cxx, scene/model/shadowvolume.hxx,
	  scene/sky/bbcache.cxx, screen/RenderTexture.cpp:
	  Harald JOHNSEN:

	  - shadow volume vertex are now shared, using DrawElements instead
	  of repeated	calls to glVertex, this can improve performance on
	  some systems.  - added a rendering path that use the alpha
	  channel instead of the stencill   buffer.  - releasing memory
	  when tiles objects are destroyed - objects sub parts will not
	  cast shadows if their name begins with "noshadow"   or if they
	  are in a <noshadow> animation

	  - bbcache.cxx :    don't ask for a 32 bits context when the
	  primary context is only 16 bits

	  - RenderTexture.cpp :    corrected a crash when asking for a
	  second rendering context    on win32 and extensions not being
	  supported

	  - model.cxx, animation.cxx :	  added a <noshadow> animation,
	  added an animation type needed by the shadow	  code.

2005-07-04 11:20  ehofman

2005-06-30 21:10  ehofman

	  Additions are likely.

2005-06-29 11:41  ehofman

	* simgear/props/: props.cxx, props.hxx: Melchior FRANZ:

	  - check for isTied() and refcount has to be made *before* we go
	  into	 recursion, so as to pertain subtrees of refcounted nodes,
	  even if there   are no refcounted/tied nodes *in* this tree -
	  return value inverted, because it's more logical to say
	  removeChildren() == true --> everything removed;  false -->
	  failed - further cleanup

2005-06-28 13:19  ehofman

	* simgear/props/props_io.cxx: Frederic: Also copy the attributes
	  over to the new tree.

2005-06-28 13:19  ehofman

	* simgear/props/: props.cxx, props.hxx: Due to a misunderstanding
	  of what removeChild() actually does, some used it to detach a
	  subtree from the main tree. The previous patch broke that
	  behaviour so a new function call detchChild() is now added.

2005-06-27 19:48  ehofman

	* simgear/props/props.cxx: fix return value

2005-06-27 15:49  ehofman

	* simgear/props/: props.cxx, props.hxx: Melchior FRANZ:

	  - introduce removeChildren() and removeChildren(name)  to remove
	  all children	 or all with a given name - let removeChild() and
	  removeChildren() also remove child trees, and let them   return a
	  "dirty" boolean that indicates if one or more subnodes had to be
	   kept because of refcounting (removeChild returned a
	  SGPropertyNode_ptr before) - make alias/unalias increase/decrease
	  the refcounter - don't remove refcounted or tied nodes

	  This patch makes the SGPropertyNode_ptr actually useful. Until
	  today, they did proper refcounting (except for aliases), but no
	  other part did check this counter.

	  But SGPropertyNode_ptr aren't only useful for the first time,
	  they are now highly recommended for every place that relies on a
	  node address, and wants to "lock" it (so that removeChild(ren)
	  will never try to remove them). This is not guaranteed for
	  SGPropertyNode* (and never was). Of course, that's not an
	  imminent problem, as only four places currently use
	  removeChild(ren) and these are careful to only remove their own
	  data.

	  This is the more elegant solution that Andy had proposed in a
	  response to my RFC on Nasal initialization code in joystick
	  configuration files.	As Nasal is initialized last (for good
	  reason), subsystem can currently not use it for initializing.

	  clouds when banking quickly - it no more rain above cloud layers
	  - add a radar echo container used by the weather radar instrument

2005-05-29 18:13  andy

	* simgear/nasal/: code.c, lib.c: Fix two crash conditions Ampere

2005-05-24 10:13  ehofman

	* simgear/scene/model/: animation.cxx, animation.hxx: Melchior
	  FRANZ:

	  Turn the material animation's <transparency> property into a
	  group, with members <alpha-prop>/<alpha>, <offset-prop>/<offset>,
	  <factor-prop>/<factor>, <min>, and <max>. The "material"
	  animation can now fully replace "blend" and "alpha-test" (-->
	  <threshold>) animations, with enhanced possibilities: The
	  "material" animation can be used for one or more explicit objects
	  (like "blend"), but also for all objects that share one material
	  (<global>), which avoids problems with objects being forced
	  together into one tree. Also, an object doesn't have to be
	  semitransparent or textured with a semitransparent texture to
	  make blending work. Unlike the "blend" animation, the "material"
	  animation also makes fully opaque and untextured objects
	  transparent. (This fixes the bo105's formerly semi-transparent
	  rotor.)

	  Erik: The blend animation and alpha-test animation are
	  depreciated as of now.

2005-05-23 18:35  ehofman

	* simgear/scene/model/animation.cxx: Melchior FRANZ:

	  Currently, the material animation sets
	  glColorMaterial(GL_AMBIENT_AND_DIFFUSE) for all material
	  properties. This breaks emission-only (e.g. cockpit lighting for
	  the p51d) or specular-only animation. ==> set glColorMaterial
	  only where it is really required.

	  This is another update for the cloud code, a lot of lines but
	  this time I have started to add the doxygen doc.

	  Misc ====

	  - corrected a bug when RTT is not available, the current
	  rendering context was   altered - if RTT is not available then 3d
	  clouds are not drawn at all - impostors lighting is now
	  recomputed when the sun changes position - distant objects are no
	  more seen in front of clouds - blending of distant clouds is a
	  bit better now - litle optimization of code (uses a less cpu
	  time) - use layer wind speed and direction (no more hardcoded
	  wind) - fov is no more hardcoded

	  Changes =======

	  - clouds (cu only) are dissipating/reforming (experimental) -
	  compute a turbulence factor that depends on surrounding clouds
	  and type of	clouds (experimental) - clouds shapes are defined
	  in cloudlayers.xml - type of clouds present in a layer is also
	  defined in cloudlayers.xml - cloud layers are generated from
	  metar and other misc. data (in progress) - added a rain effect
	  around the viewer (enabled in the rendering dialog and   when the
	  metar property says so) - added a lightning effect (enabled in
	  the rendering dialog) : cb clouds spawn   new lightnings - added
	  a dialog to select from different weather source :
	  metar/property,   a 'fair weather' environment and a
	  'thunderstorm' environment.

	* simgear/props/: props.cxx, props.hxx, props_io.cxx: Melchior
	  FRANZ:

	  Vivian pointed out that a redefined Ctrl-U key binding didn't
	  work correctly. I found out that this is, because the definition
	  in $FG_ROOT/keyboard.xml sets <value type="bool"> for binding[1],
	  and ... [better sit down first!] ... and assigning <value
	  type="double"> in a *-set.xml file doesn't *really* set "double"
	  as new type!

	  Instead, the boolean is kept, and a double sqeezed into it. In
	  other words: once tainted as bool, you can throw all doubles in
	  the universe on a property node, and all it will accept is 0 and
	  1. Without warning!

	  BTW: I changed the patch: I was overly cautious: clear_value()
	  does already care for ties and for setting NONE, so we just need
	  to make that public as clearValue(), and use that. Makes the
	  patch a bit more verbose, though.  :-/

2005-05-01 10:50  ehofman

	* simgear/bucket/newbucket.cxx: Phil Cazzola:

	  This is a minor bug fix for sgBucketDiff().  If you crossed the
	  bucket size boundary, the answer for dx could be wrong.

	  E.g.	 going from   0:0, 21:7  to 0:7, 21:7	would give you dx =
	  7 (correct)	but going from 0:0, 21:7 to 0:3, 22:0 would give
	  you dx = 6 (instead of 7)

	  Previously it differenced the center longitudes of the buckets.
	  When you cross a boundary, the center point of the larger bucket
	  now lies on the edge of the smaller bucket.

	  The result was a dx with an integer + 1/2 bucket, which rint()
	  was rounding to the nearest even int.

	  This function only seems to be used in TerraGear.

	* simgear/math/: sg_random.c, sg_random.h: Add a seed function that

	* simgear/scene/model/: placementtrans.cxx, placementtrans.hxx:
	  Mathias:

	  I have done a patch to eliminate the jitter of 3D-objects near
	  the viewpoint (for example 3D cockpit objects).  The problem is
	  the roundoff accuracy of the float values used in the scenegraph
	  together with the transforms of the eyepoint relative to the
	  scenery center.

	  The solution will be to move the scenery center near the view
	  point.  This way floats relative accuracy is enough to show a
	  stable picture.

	  To get that right I have introduced a transform node for the
	  scenegraph which is responsible for that shift and uses double
	  values as long as possible.  The scenery subsystem now has a list
	  of all those transforms required to place objects in the world
	  and will tell all those transforms that the scenery center has
	  changed when the set_scenery_center() of the scenery subsystem is
	  called.  The problem was not solvable by SGModelPlacement and
	  SGLocation, since not all objects, especially the scenery, are
	  placed using these classes.

	  The first approach was to have the scenery center exactly at the
	  eyepoint.  This works well for the cockpit.  But then the ground
	  jitters a bit below the aircraft. With our default views you
	  can't see that, but that F-18 has a camera view below the left
	  engine intake with the nose gear and the ground in its field of
	  view, here I could see that.	Having the scenery center constant
	  will still have this roundoff problems, but like it is now too,
	  the roundoff error here is exactly the same in each frame, so you
	  will not notice any jitter.

	  The real solution is now to keep the scenery center constant as
	  long as it is in a ball of 30m radius around the view point. If
	  the scenery center is outside this ball, just put it at the view
	  point.

	  As a sideeffect of now beeing able to switch the scenery center
	  in the whole scenegraph with one function call, I was able to
	  remove a one half of a problem when switching views, where the
	  scenery center was far off for one or two frames past switching
	  from one view to the next. Also included is a fix to the other
	  half of this problem, where the view position was not yet copied
	  into a view when it is switched (at least under glut). This was
	  responsible for the 'Error: ...' messages of the cloud subsystem
	  when views were switched.

	  Changes =======

	  - corrected some strange behavior when playing with the render
	  dialog options - the density slider is now working : if you are
	  fps limited and still want to see clouds in	the distance you
	  should play with that - added the choice for texture resolution,

	  choosing 64x64 textures) - changed the initial texture size : you
	  now have 64 texture of 64x64, this uses 1Mo of   texture memory
	  (before it was 20 texture of	256x256, that took more memory and
	  there was   not enought impostors) - sun vector is now right so
	  the lighting is a bit better - removed useless sort and light
	  computations for impostors, this should save a lot of cpu -
	  blending of distant cloud is more accurate now - clouds are now
	  positioned correctly, they don't try to escape you anymore - no
	  more red/white boxes around cloud - textures are now filtered (no
	  more big pixels)

	* simgear/scene/model/: animation.cxx, animation.hxx, model.cxx,

	  here is the promised material animation. It looks a bit longish,
	  but that wasn't avoidable -- there are simply too many parameters
	  to consider. I tried hard, though, to make the animation fast by
	  only doing the necessary stuff.  It doesn't affect the frame rate
	  here with my test model. The animation is heavily based on Jim's
	  "material-emission" animation.

	  * implementation of the "material" animation (this required to
	  make the   texture path available) + documentation update
	  ($FG_ROOT/Docs/) * fix some more return values (texture
	  animations, and select) for the   shadow problem (and some in
	  anticipation of other problems  :-) * fix compiler warning

2005-03-19 11:19  ehofman

	* simgear/scene/model/animation.cxx: Melchior FRANZ:

	  the cause for the disappearing shadows is, that SimGear doesn't
	  tell plib to call the pre-traversal-callback function on culled
	  objects. These calls, however, are necessary to execute the
	  transform animation that does, for example, translate a shadow
	  back into the frustum! Curretnly, the callback is only executed,
	  and the shadow only magically pops up again, when the object
	  enters the frustum because the view has changed significantly.

	  The plib documentation does only talk about TRUE and FALSE for
	  possible return values from the pre-traversal-callback. But
	  src/ssgEntity.cxx reads like this:

	     int ssgEntity::preTravTests ( int *test_needed, int which )
	     ...
		 int result = (*preTravCB)(this,which) ;

		 if ( result == 0 ) return FALSE ;
		 if ( result == 2 ) *test_needed = 0 ;
	     ...

	  So the return value needs to be 2 to bypass the cull test for
	  pretraversal, and get the pretraversal in any case. I only
	  changed the return values in four animations: scale, rotate,
	  translate, and range, because these are the most likely to move
	  an object out of the frustum. It's not necessary for
	  blend/alpha/texture manipulation etc. Of course, this is a bit
	  more work for plib, but the performance will probably not be
	  affected, because:

	  * these four animations are mainly used for the aircraft model
	  (the spin   and billboard (trees!) animations are not affected)

	  * the number of extra nodes to process is quite low

	  * a part of the time spent for the extra nodes to be processed,
	  was before   used for workarounds that are now not necessary any
	  more

	  I didn't observe a frame rate drop, at least.

	  Jim Wilson:

	  This patch adds support to the model animation system for
	  modifying emissive states on the fly so that it is possible to
	  make "lights" appear to dimm.

	  This is an example of a configuration entry which should explain
	  how it is used:

	   <animation>
	    <type>material-emission</type>
	    <object-name>Face</object-name>
	    <property>/controls/lighting/instruments-norm</property>
	    <emiss-red>1.0</emiss-red>
	    <emiss-green>0.8</emiss-green>
	    <emiss-blue>0.5</emiss-blue>
	   </animation>

	  Note the color entries are the emissive colors when the
	  "property" value is 1.0.  They are useful for tinting the light.
	   The "property" itself must be float or double and is clamped to
	  values between 0 ~ 1.0 inclusively.	The "property" value is
	  multiplied against the colors to get the actual material
	  properties.  Thus property value 0.0 = darkest, and 1.0 =
	  brightest.

	  in the ATC subsystem there will be some other bugs and nitpicking
	  along the way.

	  valgrind doesn't like that imgage->tmp is once allocated with new
	  and once with new[], sometimes with malloc() (via map), and
	  sometimes freed with delete (not delete[]!) and sometimes with
	  free(). With simple types such as GLubyte this shouldn't really
	  make a difference, but anyway.

	  Also, I promised that I'd send patches for "if (foo) delete foo;"
	  as I'm making other changes to concerned files. texture.cxx is
	  one with a few occurrences thereof. (Remember: C++ explicitly
	  allows to delete null-pointers, so this check is redundant, and
	  hence not tolerated in other projects, such as KDE. Doesn't have
	  to impress us, of course.  :-)

	* simgear/props/: props.cxx, props.hxx, props_io.cxx: Melchior
	  FRANZ:

	  My recent fix for the load/save fgfs.sav feature was a bit too
	  ambitious.  While aliases lead to abortion before, I tried to
	  copy them properly, although this wasn't a requirement.
	  Unfortunately, this seems to have worked for absolute aliases
	  only, not for relative ones, and hence broke several panel
	  instruments. The attached patch backs most of the previous patch
	  out again, and goes a simpler route: just ignore aliases.

2004-12-19 11:19  ehofman

	* simgear/props/: props.cxx, props.hxx, props_io.cxx: Melchior
	  FRANZ:

	  fgLoadFlight() loads a property file ("fgfs.sav") to a new
	  property tree, and then copies that over to the main tree.
	  copyProperties() didn't know how to handle type
	  SGPropertyNode::ALIAS and hence threw an exception that made fgfs
	  abort.

	  The attached patch adds support for ALIAS to copyProperties():
	  aliased nodes are created in the target tree if necessary, and
	  then linked like in the source tree. It seemed useful to add an
	  optional argument to props.[ch]xx/getType() that would indeed
	  return the property type "ALIAS" for aliased nodes, and not the
	  type of the node that it refers to. The patch also fixes a bug in
	  writeNode() that caused extra lines after alias entries.

	  If there's resistance to the change to getType() (David?) I can
	  easily use isAlias(). This just makes copyProperties() a tad
	  uglier, but I can live with it. It's useful for scanning a tree,
	  though, if an alias node can be treated exactly like all other
	  nodes, without automatic redirection.

	  model/model.cxx: Frederic Bouvier:

	  I was not very happy with the size of the halo, so I created a
	  new animation to control it. Now we can control the scale value
	  with the distance from the viewer to the object. The towers are
	  now beginning to look good. They might need some tuning though.
	  If you want to play, locate in radio-*.xml this code :

	   <animation>
	    <type>dist-scale</type>
	    <object-name>RedLight.2</object-name>
	    <interpolation>
	     <entry><ind>0</ind><dep>0.1</dep></entry>
	     <entry><ind>500</ind><dep>0.3</dep></entry>
	     <entry><ind>16000</ind><dep>3</dep></entry>
	    </interpolation>
	   </animation>

	  You get the idea ? ind is the distance, dep is the resulting
	  scale value.	The medium tower appears brighter than the tall
	  one, because the lights are closer to each other. Maybe they need
	  a smaller scale factor at distance. Feel free to modify these
	  values if you find a better setup.

	  About the code : I renamed flash to custtrans because the ssg
	  branch is now less specialized. It needs a callback to compute
	  the so called 'custom transformation'. It can be used for the
	  SGFlashAnimation and the new SGDistScaleAnimation. So please cvs
	  remove flash.[ch]xx and add custtrans.[ch]xx. I also undo some of
	  the code I send you yesterday that was totally useless. It is
	  replaced by something simpler and that works.

	  There is also a patch to matmodel.cxx. This is not related and
	  was something I forgot. Its purpose is to set the alpha test on
	  material billboard models that are likely to be trees to lessen a
	  transparency weird effect with clouds.

	* simgear/scene/model/: animation.cxx, animation.hxx, flash.cxx,
	  flash.hxx, modellib.cxx: Frederic Bouvier:

	  modellib.cxx :   Add a branch between the model and its
	  transformation to add  a unique identifier for the model. I
	  called it "personality  branch" and it maintains a
	  "current_object" in SGAnimation.   Animations specifically
	  written to support it ( currently only   the timed animation )
	  can add a degree of variety among the   occurrences of the same
	  model that would look otherwise cloned.

	  flash.[ch]xx :   Better compute the view vector. The flash is now
	  syncronized with  its axis even at the edge of the screen.

	  animation.[ch]xx :   Lots of changes :  - add a condition to
	  'rotate', 'spin', 'translate' and 'range'.	When a condition is
	  specified *and* it evaluates to false, the	animation becomes a
	  no-op. Possible usage : no rotation during	daylight, LOD range
	  variable along the day, ...

	   - use different durations for each branch in the timed
	  animation.
	    Enable the use of multiple <branch-duration-sec>, one for each
	    <object-name> specified. Usage : strobes with flash light.

	   - allow randomization of the <branch-duration-sec>, by using
	    <random><min>_min_value_</min><max>_max_value_</max></random>.
	    The value computed once is between _min_value_ and _max_value_.

	   - implement model personality in timed animation. If
	    <use-personality type="bool">true</use-personality> is
	  specified,
	    a different set of duration is created for every model in the
	    scenegraph using this animation. Best if used with
	  randomization.
	    When using strobes where the population of the same object is
	    dense, it avoids the "cheasy" clone effect.

	* simgear/scene/model/: Makefile.am, animation.cxx, animation.hxx,
	  flash.cxx, flash.hxx, model.cxx: Frederic Bouvier:

	  this patch introduce a new kind of animation and ssg branch.	I
	  called them flash animation, because they help me to enhance the
	  look of the rotating beacon and possible future lighthouse. It
	  computes the cosine of the angle between an arbitrary axis,
	  transformed by the current modelview matrix, and the view
	  direction. No trig involved, just a dot/scalar product.

	  The computed value can be modified by three parameters, power,
	  factor and offset, according to the formulae :

	   value = factor * pow( cosine, power ) + offset.

	  It is clamped between a minimum and a maximum.  This value is
	  then used as the scale factor of a matrix transformation applied
	  to the children of the SGFlash branch.

	  The xml syntax, with default values, is :

	  <animation>  <type>flash</type>
	  <object-name>HaloObject</object-name>  <center>   <x-m>0</x-m>
	  <y-m>0</y-m>	 <z-m>0</z-m>  </center>  <axis>   <x>0</x>
	  <y>0</y>   <z>1</z>  </axis>	<power>1</power>
	  <factor>1</factor>  <offset>0</offset>  <min>0</min>
	  <max>1</max>	<two-sides>false</two-sides> </animation>

	  This is a new patch that allow to define a different texture for
	  top and bottom of clouds. It uses the overcast_top.rgb you made
	  for me last time.

	  What the patch do is to install a ssgStateSelector instead of a
	  ssgSimpleState for each layer.  The SGCloudLayer::draw method is
	  modified to accept a boolean that will select the proper state:
	  0/false for bottom, 1/true for top.

	  Then, in SGSky::drawUpperClouds and SGSky::drawLowerClouds,
	  SGCloudLayer::draw is called with false and true because we see
	  the bottom of upper clouds and the top of lower clouds.

	  Only overcast has 2 textures, the other types share the same
	  state for top and bottom, but that could be modified in
	  SGCloudLayer::rebuild.

	* simgear/scene/model/location.cxx: Frederic Bouvier:

	  The message 'Alert: catching up on tile delete queue' comes from
	  the fact that 48 tiles are scheduled and added to the cache at
	  startup before the plane location is initialized. My proposed
	  patch is to initialize SGLocation with an invalid position and
	  detect this fact before scheduling tiles. I prefer to do that
	  rather than testing for lon and lat being 0,0 because it is a
	  valid position and someone could want to fly near Accra.

	  Frederic Bouvier: This patch is there to correct a problem that
	  prevent to load static objects when specifying a relative fg-root

	  mix between fg-root, fg-scenery and PLIB's model-dir.  It has
	  been reported on the list that users are not able to see the
	  buildings, especially those running the win32 builds because they
	  run 'runfgfs.bat' that set FG_ROOT=./DATA.

	  I decided not to use model-dir because it just add confusion and
	  to build a valid path earlier.

	* simgear/scene/model/: animation.cxx, animation.hxx, model.cxx:
	  Jim Wilson: This update adds the ability to do multiple texture
	  transforms (Steve B. thinks supporting them at the plib level
	  would be inefficient, which is probably true).

	  Removed units (e.g. "_m") from texture translation property and
	  variable names since the texture translation values are
	  dimensionless.

	  Added the ability to specify a scroll factor for stepped texture
	  animation that needs to scroll smoothly when approaching the step

	  Jim Wilson: 1. Added support for defining arbitrary rotation axes
	  using (x1,y1,z1), (x2,y2,z2).  The center is calculated
	  automatically (midpoint on line) or you may specify an alternate
	  "center" using the current scheme.  This makes it about  100
	  times easier to animate flaps, ailerons, etc.

	  2. Added support for plib's ssgTexTrans.  This will allow more
	  sophisticated 3D instrument features by allowing the texture
	  mapping itself to be animated. Included function for "texrotate"
	  and "textranslate".  They configure the same as the geometry,
	  except the arbitrary axis definition is not necessary (textures
	  are flat).

	* configure.ac: James Turner:

	  I've had to hack Simgear's configure.ac quite a bit [for Mac OS
	  X], using the Plib one as a reference.  The basic construct (a
	  big switch statement based on the target type) is nice, I think,
	  since it moves lots of IRIX / cygwin / OS-X specialties out of
	  the way cleanly. Much more re-factoring of the current tests in
	  configure is possible if people are able to test.
