variation. To do this, set extra_float_digits to -3 in the geometry test, and tweak the CIRCLE_TBL dataset to avoid values that suffer from severe cancellation error (eg, circles that just touch an axis). We still need two geometry 'expected' files to account for the difference between platforms that display minus zero as '-0' and those that just say '0', but with luck that's all we'll need.
