- this exposed a bizarre issue on Mac where dragging in <AGL/agl.h> in
extensions.hxx was pulling in all of Carbon to the global namespace
- very scary. As a result, I now need to explicitly include CoreFoundation
in fg_init.cxx.
- change SG_USING_STD(x) to using std::x
own preferential runway support. In future versions, we might want to
condider having a more generic mechanism for this.
- Keep a history of active runway for each class, so that runway assignments
are more consistent after whether updates or time-related schedule changes.
I refactored the XML loading code out of FGAirportDynamics and
FGRunwayPreference. I also added a new class XMLLoader, which serves as a
facade to the loader functions. Further I changed FGRunwayPreference to just
keep a FGAirport ref, which is more concise and closer to the right(tm)
solution than storing the airport data a second time ;-)
The original code selected the most preferable runway combination,
regardless of which combination was currently active. This patch
builds in some additional resistance against change, by keeping
track of which runways are already in use, and forces a change
in active runways only when new (wheather/time of day) conditions
force it to do so, resulting in much more consistent runway assignment.
behavior.
