box_contain_point() also doesn't use the macros. They are certainly
inconsistent, but I don't think it would be an improvement to make
them use the macros. As we have discussed, there are many problems
with the current application of EPSILON. I think we would be better
off not using the macros for none of the containment operators, but
this is out of my scope for now.

I am waiting the rest of your review to post the new versions.
