Intersection semantics

We should define what a border hit should do for all intersection tests.

One action item to take - see what other libraries are doing. In general, I'm fine with either decision as long as it's consistent ;)

Yeah, I tried finding information on this, but my google skills apparently aren't up to the task, and I'm not sure what open libraries there are except for ncollide.

ncollide seems to report a hit on border intersections. It's hard to tell ...

Related point would be checking the returned values on edge cases. ncollide for example had issues at 0 penetration depth, resulting in bogus normals returned from the hit test.
