47771c9bb4 Several changes related to [trying to] make more effective use of the global 
land cover/land use raster data, but there seem to be some very significant

5937926a0b Ok, big oops here. I was passing 3 parameters to a 4 parameter function, 
but because of the use of default arguments, the compiler wasn't flagging
this as an error.  This caused a) much stupidity and b) additional stupidity.

I also found a case where I passed in a length and width extention parameters
but, used the length parameter twice ignoring the width parameter.  This
yields much more sensible and expected results when building the grass buffer
zone around a runway.

730c454320 - Test a different approach for assigning land cover attributes to "default' 
cover" areas.  Rather than artificially cut in polygon areas, just lookup
  a land cover type for unassigned triangles.  I think this has potential, but
  it needs more work to eliminate some odd artifacts.

- Revove --min-angle= option.

- Don't re-fit() triangle array to try to achieve a particular range of
  node quantities ... this is all pre-computed with a much smarter, much
  more efficient algorithm.

bab9af52b3 Just ignore "void" data points when doing the surface fit. I think this

9c85f16b5f Working towards the ability to specify elevations for a polygon in it's

airports and runways of course as well as roads, rivers, streams, railroads,
or any other object where we might want to control the final elevation in
advance.

bb4c4f6b13 First stab at a utility to fetch scenery based on the current flightgear 
position.

Terrasync runs as a separate process and accepts the --atlas=port format.
The fgfs output tells the terrasync util where FlightGear is currently flying.
Terrasync will then issue the appropriate commands to rsync the surrounding
areas to your local scenery directory.

As you fly, terrasync will periodically refresh and pull any new scenery tiles
in the vicinity.

This also works if the scenery on the scenery server is update.  Rsync will
pull any missing files, or any updated files.

There is a chicken/egg problem when you first start up in a brand new area.
FlightGear is expecting the scenery to be there *now* but it hasn't been
fetched yet.  I suppose without making a more complex protocol, the user
will need to be aware of this.  The user could restart flightgear after the
initial rsync completes, and then after that everything should be good,
assuming the user has the necessary bandwidth to keep up with flight speeds.

Final notes:

At the moment Alex Perry has a partial rsync server, but I don't know it's
status.  I hope to have a full server up and running at some point soon.

Currently the terragear utility just echos the commands it would run to
rsync the data, it doesn't actually run the commands.  This is a work in
progress.

This prevents portions of the approach lighting system from dipping below
ground level in cases where the surrounding terrain is simplified and doesn't
perfectly match the DEM data.

5f502fc76b This falls under the oops category or perhaps I was uncharacteristically 
confused by the alphabet soup.

9f6fdee612 Use wgs_84 math to layout runways. My original method was a little backwards, 
it involved creating a 2d runway object of the right size, rotating it and then
trying to back solve for the actual lon/lat.  This and a few other problems was
causing problems with subsequent texture coordinate calcs for the runway
surface textures.  It also could have contributed to runways/lighting being
slightly misaligned with the ILS's.  Then lots of minor cascading changes as a
result.

fbb232280e Frederic Bouvier: 
Well, I found a bug in VpfTile that prevents the function getTileSubdir
to return the correct value.

In that case getTileSubdir was returning the content of a local
variable (subdir) that is destroyed before used outside. Usually,
it generates a segfault with MSVC but here, the returned string
was "". The patch returns the value of the string and tgpvf is
going well so far.

58634b2dfc - use SG_LOG throughout instead of cout/cerr

- replace all instances of exit() with an exception throw, caught in
  main.cxx, so that the program can go on processing the rest of the
  airports; to restore the old behaviour, just add an exit() to the
  catch clause

(Unfortunately, this still does not guarantee a full processing run,
because triangle.c in the library can invoke exit() when it gets
hopelessly confused.)
