See previous commit for partial rationale. There's an argument to be made about the `NaN`-spreading semantics being desirable because at least something will loudly fail in that case, but I'm not so sure about that these days. It feels like either way if `NaN`s are produced, then things are outside of any control, and chances are the game can probably continue without crashing. And, this move reduces our dependence on osuTK, which has already been living on borrowed time for years now and is only awaiting someone brave to go excise it.
