	<brief_description>
		Animation player that uses a node graph for blending animations.
	</brief_description>
	<description>
		A node graph tool for blending multiple animations bound to an [AnimationPlayer]. Especially useful for animating characters or other skeleton-based rigs. It can combine several animations to form a desired pose.
		It takes [Animation]s from an [AnimationPlayer] node and mixes them depending on the graph.
