There used to be a hardcoded visibility of 1000m below which the
sky was disabled. This distance is now bound to
/sim/rendering/minimum-sky-visibility with a default value of 1000
- initialize uninitialized properties
- use prefix instead of postfix increments
- reduce visibility of variables
- use empty() instead of size() == 0 for vector and string
- pass string by reference, not by value
Only draw 3d clouds if enabled and shader-effects are true.
Remove the property-tie for 3dclouds-enabled and use a change listener
instead which also listens for changes of the shader-effects property.
Compute gravitational acceleration based on the formula of
Somigliana corrected for altitude and provide the value
in property /environment/gravitational-acceleration-mps2
1. The atmospheric properties of FG are not yet initialized when
JSBSim is initialized.
-> patch is quite basic and there may exist smarter ways to initialize
properly the environment before the FDM.
2. The Euler angles were initialized after the velocities.
3. The glide slope and rate of climb were ignored. Fixes all FDMs (YASim,
UIUC, JSBSim, etc.)
4. Some properties were instructed to re-use their previous value while
they should not.
5. Some bugs existed in JSBSim trim code. -> This bug has already been
fixed in JSBSim but the corresponding patch has not yet been applied to FG.
This class and their source files visual_enviro.[h|c]xx were
unused since OSG transition. It's only functionality was to
keep a variable for the enable-state of rendering of precipitation.
This has now been moved to SGPrecipitation.
This patch also removes all references to this class and
visual_enviro.hxx. Wxradar needs a new implementation for cloud
echoes which probably should be part of fgclouds.

New "auto-position" switch to always use closest tower for tower-view.
Exposes new "/sim/airport/closest-airport-id" property.
Display closest airport on groundradar by default.
Untieing needs to be done prior to the destruction of the object which
aggregated the TiedPropertyList. So the TiedPropertyLists destructor can't
untie the properties automatically (and it doesn't). So, do some manual
clean-up.
SGCloudField::addCloud does *not* keep a reference to SGNewCloud - so we
only need a temporary object. Also adapt to changed addCloud interface
to make things a little more obvious.
Catching loader thread on subsystem destruction is too late, since it
depends on other subsystems (which are destroyed earlier).
=> Need to stop & join thread during subsystem shutdown.
Also changed loader sleep logic - to avoid excessive delays (up to
30 seconds) on shutdown.
(Issues mostly happened when running offline with realwx enabled.)
