Duplicate an animation, except rotated by the specified number of degrees. For example, if you have a single animation (0), and you want to rotate it by 90 degrees, it will create animation 1 with that rotation to it. In the long haul, generating a few rotated animations is less memory intensive than rotating it on demand using the MirrorHorizontally or MirrorVertically booleans.

public void AddAnimation(
	int AnimationToCopy,
	bool MirrorHorizontal,
	bool MirrorVertical
