Last frame of entity animations might be sticking for an extra game frame

This is easier to see at a lower FPS like 10 or 15. I wanted to avoid a while loop there since that would probably be too slow for thousands of entities.

I might be misunderstanding the problem and this is just how it would be due to beat frequencies or something? Anyway, changing it to this seems to have no change:

this->currentSeconds += dt;
if (looping)
{
	while (this->currentSeconds >= totalSeconds)
	{
		this->currentSeconds -= totalSeconds;
	}
}

I think this was fixed with the software renderer part 1 refactor. It's still kind of noticeable but it isn't always the last frame, so I think it's a beat frequency thing that varies based on the difference between the entity's frame rate and the game's, which is okay.
