Avoid copying drawables and dirtying display lists.
For the alpha-test animation, use an OVERRIDE attribute on the state
set of the top level node instead of copying drawables and state sets
throughout the model.
As a temporary hack in the blend animation, don't use display lists in
the cloned drawables.
These changes are aimed at cutting down the number of display lists
that the pager needs to compile.

In the original flightgear native/binary scenery terrain data format, we
used short's extensively to represent counts of objects (number of points,
number of texture coordinates, number of traingle strips, etc.) and we used
shorts to index into larger structures. But this capped many of our structure
sizes to a maximum of 32768.
By switching to unsigned shorts in the future, we can double the maximum
object/index counts without losing anything. This was a pretty major
oversight in our original specification.
I have bumped up the native object file version from 6 to 7 and added code
in the reader to maintain full backwards compatibilty with version 6
scenery files (i.e. the current 0.9.10 scenery release.)

Don't reset the random texture base when rebuilding a cloud layer
This fix removes obnoxious visuals (texture jumping) when a cloud
layer is moved due to a metar update or, more significantly, when
switching from metar to a scenario. Also, I switched to using a TexMat
to displace the cloud texture in order to avoid writing the texture
array every frame.
Put the ocean tile state set in osg::Geometry, not the osg::Geode, so that
is readily available during intersection testing and can be used to find the
corresponding SGMaterial.
Fix material animations with only a <texture-prop>

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> alone l. 379ff.
Unless I overlooked some compelling reason contradicting, I'd like to
suggest allowing for a stateSet to be created for those situations
too. I think that would match the behaviour of animation.cxx
(PRE_OSG_PLIB_20061029) and is imho the more expected and also
documented one.

Maik JUSTUS: workaround for broken Doppler effect in OpenAL
mf: this patch is meant to be removed as soon as OpenAL got fixed. (The
OpenAL developers acknowleged the bug and announced that it'll get
fixed.) For removal try
$ cd simgear/sound
$ cvs diff -rAFTER_OPENAL_DOPPLER_WORKAROUND -rBEFORE_OPENAL_DOPPLER_WORKAROUND|patch
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.
- 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
replace exit() by throw sg_exception(). Of course, we have to be aware
that 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)
add SG_ORIGIN macro that expands to a string __FILE__":"__LINE__
Note that __LINE__ is a number and can't be directly used in string
context, which makes the macro worthwhile. (IMHO :-)

- fix bug where a property tree saved with writeProperties() and read back

- introduce "omit-node" modifier attribute for the "include" attribute.
This inserts the given file in place of the including node, while the
