Easing Functions

Take a look at the following animation.

val bubble =
  Reactor.linearRamp(0, 200)
    .withRender(r => Image.circle(r))
// bubble: Reactor[Double] = Reactor(
//   initial = 0.0,
//   onMouseClickHandler = doodle.reactor.Reactor$$$Lambda/0x00007f7b46277798@3b399202,
//   onMouseMoveHandler = doodle.reactor.Reactor$$$Lambda/0x00007f7b4627c000@67d2ba1b,
//   onTickHandler = doodle.reactor.Reactor$$$Lambda/0x00007f7b4627a1f0@38f7954a,
//   tickRate = 100 milliseconds,
//   renderHandler = repl.MdocSession$MdocApp$$Lambda/0x00007f7b46279000@1c49a040,
//   stopHandler = doodle.reactor.Reactor$$$Lambda/0x00007f7b4627a5d0@6b179849
