Use an entirely different method for area computation. It first transforms to a 2D plane by interpolating the great circle arcs through a Lambert azimuthal equal area projection. Then a standard 2D polygon area method is used.
Make sure the polygons always go clockwise to aid in area computation. Fix union calculation -- it should be removing interior edges, not interior nodes. Fix some numerical out-of-range problems in great_circle_arc.py Remove the serial method for multi_union -- it no longer generates polygons that are compatible with calculating the area. Make debugging images more explanatory by putting a meaningful title at the top. git-svn-id: http://svn.stsci.edu/svn/ssb/stsci_python/stsci_python/branches/sphere@17200 fe389314-cf27-0410-b35b-8c050e845b92 Former-commit-id: fb841a481025150f631be6d64cf995dda592ecbc
