-		[AnimationNodeBlendSpace1D] represents a virtual 2D space on which [AnimationRootNode]s are placed. Outputs the linear blend of the three adjacent animations using a [Vector2] weight. Adjacent in this context means the three [AnimationRootNode]s making up the triangle that contains the current value.

 		You can add vertices to the blend space with [method add_blend_point] and automatically triangulate it by setting [member auto_triangles] to [code]true[/code]. Otherwise, use [method add_triangle] and [method remove_triangle] to triangulate the blend space by hand.
