Right Epsilon for 6 decimal GeoJSON ?

[cyrilchapon]

What would be the best epsilon for GeoJSON with 6 decimals coordinates ?

With tests, 0.00000000001 (1 x 10^-11) is ok while 0.0000000001 (1 x 10^-10) is not

FYI, there is an open PR for better (?) epsilon calculations, here:

I haven't tested it in depth, but maybe it is worth your time.
