This will allow us to perform access control validation in SimGear. The
current implementation of SGPath::validate() is 99% Rebecca Palmer's
work (see fgValidatePath() in FlightGear commit
6a30e7086ea2f1a060dd77dab6e7e8a15b43e82d); only the coding style has
been slightly modernized here since we can now use, for instance,
C++11's range-based for loop.
This is to avoid confusion because the following commit will make
SGPath::validate(bool) replace the fgValidatePath() function from the
FlightGear repository.
- Add an explicit constructor SGSoundSample(const SGPath& file) that
directly uses the specified path instead of going through
ResourceManager::findPath().
- Reimplement the existing constructor as
SGSoundSample(const std::string& file, const SGPath& dir),
delegating to the new one.
- The first argument of the delegating constructor is now a
const std::string& instead of a const char*.
Among others, this will allow a better implementation of
FGSoundManager::playAudioSampleCommand(). More explanations can be found

Previously 3D cloud re-position code did not re-orientate
the sprites, leading to the sprites being at an angle for
long flights.
Fix from Michael DANILOV to address this.
The assumption is that all images coming from Canvas should be excluded from inclusion into the DDS texture cache.
Previously there was special logic that only excluded transparent images of Canvas origin but this was probably wrong.
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.

The random lights placement algorithm was using the incorrect channel
from the object mask image, (red instead of blue as mentioned in
Docs/README.materials). This commit rectifies the mismatch.
The Canvas camera and texture get recreated in several circumstances.
Calling .release() on a ref_ptr will just return the raw pointer and
'delete' won't be called. The proper way to explicitly delete an object
managed by a ref_ptr is to set the ref_ptr to NULL. This will delete it
as long as it's not referenced by any other ref_ptr.
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.
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.
