e93197d1b5 David Luff: 
Attached are patches to Terragear to enable it to compile out of the box on
Cygwin (once all the relavent libraries have been compiled).  Specifically
they fix a conflict with another version of min/max somewhere on the
system.

ced60ae2e2 Remove IOSTREAMH macro -- it turned out to be something specific to

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.

curt
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.

f5f961b8c0 Remove support for a "minimum triangle angle" quality constraint when

bab9af52b3 Just ignore "void" data points when doing the surface fit. I think this 
is probably better than guessing at a value and fitting to the guessed value.

For corner points (where we *need* a value to do the fit) use the elevation
of the "closest" euclidean-wise valid point.

68a4ac7956 Added a small test program that builds a simplified surface approximation

Essentially start with two triangles forming the bounding surface.
Then add the point that has the greatest error.  Retriangulate.
Recalcuate errors for each remaining point, add the one with the
greatest error.  Lather, rinse, repeat.

d70cd72fbd Don't automatically try to preserve polygon elevations, but instead provide

c5ab6678f2 Added support for including height information in the intermediate polygon

I needed to add code to preserve the elevations in the clipped output and

clipping.

9c85f16b5f Working towards the ability to specify elevations for a polygon in it's 
intermediate mode.  The goal then is that these elevations would be
preserved throughout the tile construction process and the surrounding
geometry would fill in without gaps.  This has potential applications for
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.
