- 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
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.
