TimeFrame()
Either calls TimeFrame() from the generic runtime, or is re-implemented to
better fit the engine/environment that the runtime is made for.
function TimeFrame(
time: Time,
animation: Animation,
reverse: Bool,
isLoop: Bool,
) {
GenericRuntime.timeFrame(time, animation, reverse, isLoop);
// or, copy it's implementation with a more appropriate Time type from the engine
}
