Until we have a way to mark techqniues as permanently disabled,
remove this check, since it generates false positives. Especially,
see model-combined technnique n=9.
Pass the full path to the XML file, not is containg directory, through
effects, so that it's available for error reporting. Convert to an
actual directory when using the path to lookup other resources.
We had a manual change in ShivaVG, to include the shConfig.h file
explicitly, since the sources do not include it themselves. Replicate
this change in our copy of ShaderVG.
Necessary to fix compilation on macOS and likely FreeBSD as well.
Consider non-empty containers and non-nil objects (eg, ghosts) to be
true-like, in boolify(). This makes for more natural testing of return
values.
Since these types previously caused a runtime error, should be backwards
compatible, unless code was relying on the error. This seems improbable,
if it happens in practice, we can revert and find a different solution.
getrandom() is only in GLibC >= 2.2.5, and CentOS 7 uses an older
GCC version, so add CMake logic to fallback to /dev/urandom as the
Expat entroy source.
Need a grid layout in addition to the existing vbox/hbox layouts,
add a basic one. Still work in progress, minimal test cases pass.
No height-for-width support yet, but row/column spanning and stretch
factors are supported.
Move some functionality from Layout.cxx into BoxLayout.cxx, which
is specific to the one-dimensions layout types.
Required to address reported in-the-wild CVEs in older Expats.
This may need a tweak for Linux / BSDs to set appropriate values in
our custom expat_config.h : only macOS and Windows tested so far.
This gives knowledge of how to resolve relative paths, to makeEffects
invocation of findDataFile, and hence gives a more familiar lookup
ordering, for Aircraft-supplied effects.

Throwing an exception causes normal error-collecting to trigger for
the XML model load, so this is sufficient to avoid the crash and
also report back to the aircraft developer & user.
Thanks to Michael Danilov for catching this.

To simplify various rounding / truncation operations, especially when
dealing with frequency values, give floor() the same precision control
already present in math.round(), and add math.trunc() which always
truncates towards zero.
Attempt to narrow down the source of some fatal exceptions we see
on Senty, which occur during init/startup. All these blocks re-throw
so user behaviour is unchanged, but we’ll log the name of the subsytem.
Use an exception rather than polling a flag, for checking errors
during BTG reading. This should allow us to give a correctly
identified error, at exactly the point the read fails.
When an effect defines no shader sources, special case this error to
avoid confusing result from SGProgram.
Add error-context for readNode STG loading, so failures inside an
STG can be attributed
Report errors from readWAV, and improve attribution for the
format error (include the file path). As a result, mark the individual
exceptions as dont-report, since we will report higher up.
Fixes an error case where a manual TerraSync server is specified; we
would attempt to use an empty string as the OSM2City server, with
hilarious consequences.

Ensure the STG absolute path can be propagated to all files triggered
by STG loading, including the delayed files and proxied files. This
allows us to attribute errors to the correct scenery path.
Allow us to pass the current error-context from the main thread
into the osgDB loader thread. This is necessary so we can attribute
AIModel (etc) load problems to the correct source.
Move sg_location member up to the base clase, since it’s potentially
useful in more types.
Allow suppression of the report callback when the exception is thrown
Fix the cull callback to continue with normal culling. Also move
where the particle frame is added to the scene graph, to be sure
we don’t modify the scene during OSG traversals.
Ensure all data members are correctly re-initialzied when doing a reset.
This shoed up as negative ‘bytes downloaded’ counts after a TerraSync
abandon and retry.
Extend our own particle manager to replace the OSG particle system
updater. This fixes thread-safety and also timing (better match to
simulation dt values). We also use weak pointers (observer_ptr in
OSG terminology) to ensure particle systems are released once their
frame is gone.
