Issue with new mac compilers result in precision differences with very small numbers
This causes failures in the test comparisons between mac runs and reference
FIX TEST: change test to avoid square, make vertical length shorter than horiz.
FIX TEST: or set user value for epsilon zero volume
For "degenerate" cases with 4 vertices on circumscribed circle, you can put the diagonal edge of the rectangle on either diagonal and round off may be the deciding factor. Different connection of degenerate case is still correct/Delaunay.
NOTE files written without zero coefs are the same:
output_mac/out_hex_3x4.uge output_linux/out_hex_3x4.uge
Files with all coefs including zero coefs differ:
diff output_mac/out_hex_3x4.stor output_linux/out_hex_3x4.stor
