- 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.

For corner points (where we *need* a value to do the fit) use the elevation
