Issue description:
Hello. I try to make 8-way animation by using BlendSpace2D, but after change blend_postion it has small time lag before animation changed. I think, it's wait when current animation finished.

This is not really a bug, blend tree is for blending and animation frames are not something you can "blend".
I wonder though, if maybe we could add a "discrete" mode, so animations are re-started instead of blended in such cases..

@reduz Hello. Thanks for fix 👍 But why did you change the API of animation nodes? AnimationNodeStateMachine has method travel and BlendSpace2D has variable blend_position, now it can only be obtained through parameters of AnimationTree. It's bug or feature?
