title: Animate a shape along a line or path in konva
body: <p>Is it possible in Konva to animate a shape (marker, circle) along a lline/path. I tried to manually calculate positions over time but this is only feasible if the line is straight from A to B, but I'm interested in a bezier curve and multiple path points.</p>
  
  <p>So I wonder if Konva supports this kind of thing or someone could give a direction how to approach this.</p>
