Subject: [ggl] Difference / xor for multi polygons

Hi Javier,

Right, now I get the same. The error occurs only for double. For float
it is OK (but that is by chance), for ttmath it is also OK (that is as
intended). The differences in coordinates are so small that for double
they probably cannot be represented, but this is my preliminary
conclusion. I will check if I can get extra information, and if there
are even possible solutions. This can take me a while.

For checking coordinates like this, I would advice to use ttmath.

Interesting tests.

Regards, Barend
