is too close to level

Peter Barker 51a0401383 AP_Math: correct Polygon_outside floating point instatiation
This routine was entemplatificated from the integer version, which was
designed to be perfect across representable ranges of points.  The
floating point version suffered from a rounding problem.

Peter Barker ce53ae63ae AP_Math: use /2 in place of *0.5f
MdB says:

dividing by 2 is actually optimal. It's type correct for all usage, and the compiler generates the multiplication if it's float, and sticks with divide for integers

Godbolt indicates on any optimization level (O1-O3, and Os) that the compiler will correctly optimize the / 2 into a float multiplication if using a float, but if using integer types in the template it will stick with the / 2 which is faster then doing the conversions to/from float.
