add an optional parameter that would be called to
build the aircraft panel, so that flightgear's
model_panel no longer duplicate code.
add a pretrav callback to models so that we can
filter out models when calling ssgCullAndDraw on
the global scene.
sgSetModelFilter( true ) means that we want to draw
the models. Use false to cull them out.

Fix GC interaction. The "me" reference to a method call was being
popped off the stack in a situation where it could be garbage
collected. I believe this is the source of the spurious "non-object
have no members" bug that has been reported.

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.

This patch is for windows only. It hides the console window

that I think is the right way to display something in FG.

Work around a limitation of gc_calc_course_dist(). When the start and end
points are too close together, this routine can return a course of "nan"
but the distance is valid. Someday someone who understands the math should
rewrite the gc_calc_course_dist() routine so it is more robust, but for now
it's easiest to simply check for a nan result and code around the limitation.

Make it possible to define multiple texture for a material (multiple <texture> entries in the materials.xml file). The code can return a random texture, or a pre defined texture upon request (default is random)

Here are some updates for the metar class:
- support for empty visibility group
- support for 4-alnum IACO ids (rather than only 4-alpha)
- better diagnosis in exception messages
- check for 404 http response
- replace last constant by constants.h definition

Fix from Richard Harke for 64 bit systems. The reftag was left
uninitialized by naNum(). If it happened to be constructing it on the
stack in a location previously occupied by a real reference, it would
generate a corrupt naRef.

Yank the MSVC special handling. It turns out it was becuase "strlen"
has special voodoo in the parser. That's much more cleanly handled by
renaming the function than by #ifdef'ing.

Oops, I originally had ramped the vasi/papi color transition the wrong way.
So as you passed through the target glide slope from low to high it would
be colored: red -> white -> small range of transition to red -> white.
Now it goes the right way so you get: red -> smooth transition to -> white.
You can tell you are getting high if you see the bottom vasi start to turn
pink ... etc. etc. hopefully just like in real life.

The emissive values just don't seem like the right thing to do. You suddenly

The rest of the moon still seems a bit oversaturated right now ...

The attached patch adds a new animation class, called SGAlphaTestAnimation, to enable alpha test in 3D models.
This will remove many artefact caused by painting order of translucent models, and I need it for an upcoming model. In addition, I added a min-factor and a max-factor to the range animation to modulate min-m, min-property, max-m or max-property.

Rewrite sg_geodesy. The new version is more accurate to the WGS84

There's another problem with sg_socket.cxx: the timeout value is
hardcoded as 0. This is appropriate for servers as they continuously
poll the socket and never want to wait for clients. But clients
*do* want to wait a few seconds for a server response.

Extra i++ led to a "double skip" when parsing a \r\n pair. So a DOS
