Norman,

Thanks for your continued work on this section of code.

Just a quick report for those that may want to try this code out
before some fixed version of this can be put in cvs.

I had to copy sgdPointInTriangle() as well as one other routine from
the old hitlist.cxx to get things to compile.  We made a decision a
while back that we wouldn't require a development version of plib,
but require only the most recent 'stable' version.  So, these routines
need to be included.

I'm finding that I get wrong elevations reported for portions of
airports that span multiple tile boundaries.  Such airports are
attached to one particular tile in the scene graph, but they can
extend into neighboring tiles.  For instance, KBOS (Boston) sits right
on top of the corners of 4 tiles.  However, in the scene graph it is
root below only one tile (chosen arbitrarily for all practical
purposes.)

I don't know if that helps you track down what's going on.  If no one
else can reproduce this problem in this latest code (from Norman's web
site, not yet commited to cvs), then let me know ... maybe I screwed
up something on this end.

Being that this code is critical to the overall operation of the sim,
I can't commit these changes just yet.  We obviously need something
that works reliably in every situation, even if it isn't as optimal as
it could be.

Hopefully it's an easy fix ... (?)

Thanks again,

Curt.
