Add a constructor or utility function to convert a Path to a PathData

[KennyGoers]

Feature Request:

I need to manipulate a PathData by rotating it into position BEFORE adding it to a Node, think compass needle animation. The Needle is kept at 0 heading and needs to be rotated to its starting point before animating to its end point. The method is there to convert from PathData to Path, but need vice-versa

Don't think this is feasible, but I think one thing I could potentially do is add a method to allow people to specify a Path object itself inside of the PathNode.Builder or something like that.
