40170cb722 The view frustum is defined in plib apps using calls to ssgSetFOV() and 
ssgSetNearFar().  This by default creates a symmetric view frustum which is
typically what an application wants.

However, to get control of the view frustum in order to build support for
asymmetric view frustums, we need to wrap these calls with a bit of our own
logic.

This set of changes wraps all calls to ssgSetFOV() and ssgSetNearFar() with
FGRenderer methods.

I also standardized how the FGRenderer class is handled in globals.[ch]xx.
This led to some cascading changes in a variety of source files.

As I was working my way through the changes, I fixed a few warnings along
the way.

439a9fa1e4 Minor API changes to support the new sg_geodesy implementation. A few 
places now use sgCartToGeod() instead of rolling their own
approximation.  And YASim is now using exactly the same 3D coordinate
system as the rest of FlightGear is.

a217c563ba Clean up the timeofday setting code a bit more, consolodate the solver 
functions (note to Norman: I looked at the web page you listed and that
looks like a good idea, but I don't have time right now to go through and
debug an entirely new routine.  What we have works well enough for now I hope!)

7a29fc0613 Average sunlight and ambient light instead of multiplying it 2003-08-29 22:13:05 +00:00

27a36e6059 - The latest volley in the FlightGear lighting wars. 
- Ambient is based off the lookup table only.
- Diffuse is based off of the lookup table, but multiplied by a combination
  of sun/fog colors.

The result is a bit more ambient light at dusk and night since the world is
never 100% dark.  And we still get nice sunset/sunrise colored illumination
of surfaces that are directly illuminated by the sun.
