Use CheckedNumeric in BiInterpolImpl
This CL splits up BiInterpolImpl into the three interpolations its made of. In the interpolation, safe math is used, and a boolean keeps track of whether an overflow has occurred. If it does, we consider the patch to be invalid and immediately terminate the Draw method.
