+			return (abs(Min.X - rhs.Min.X) * 2.0f < (Size.X + rhs.Size.X))


There is Vector::abs method (or at least should be), use it.

BasicMath.hpp has Poly::abs for float, double and long double overloads but no Vector.

Ok, I added this to trello.

please check your indentation setting in the IDE. These files are all over the place.
