Contributions from David Megginson.
...
- increased maximum areas to 128 (for future growth), and added Road
and Railroad areas
- changed the method of calculating the triangle centre in
poly_support.hxx
- added a has_holes() method to polygon.hxx
- added a new library, e00, for reading ArcInfo e00 files (i.e. the
free online ones from DCW and GeoGratis); it needs more work
- added a new prep utility, e00lines, for creating textured polygons
out of e00 line data (with user-specified width and area type); this
is useful for roads, railroads, rivers, and utility lines

normal calculations.

This code does a lot of malloc()'ing of space, and in some cases blindly
...
expects the results to be zero'd out, even though this may not be gauranteed.
So I (Curt Olson, curt@flightgear.org ) have added some code here
to explicitely zero out the space after it is malloc()'ed.

Fixed a bug that occured when an airport was located on a tile corner. The
...
first tile to build that corner gets to define the shared point, but since
it was clipped out by the airport hole, the value defaulted to randomness.
This was then propogated on to adjacent tiles. I now calculate the corner
value in advance so the code is not dependent on finding the corner in the
resulting point set.
