Fading fades everything, should only fade the specified Entity. #18

Example:

import nanim

proc myScene(): Scene =
  let
    scene = newScene()
    dot1 = newDot(100)
    dot2 = newDot(100)

  scene.add(dot1, dot2)

  dot1.moveTo(200, 500)
  dot2.moveTo(800, 500)

  scene.play(dot1.fadeOut())
  scene.play(dot2.fadeOut())

  return scene

when isMainModule:
  render(myScene)

I expect first dot1 to fadeOut, then dot2 to follow. Currently, both fades out at the same time: fade

Found it.

in init(entity: Entity) I use the defaultStyle, which for some reason causes it to be mutated within the interpolations. By changing it to be defaultStlye.deepCopy() in the initialization this is fixed. Will be included in next version bump.
