// Path has 3 endpoints: (0,0), (100,0), (100,100).

// keyTimes="0;0.25;1" with dur=4s means:

//   keyframe 0 occupies t=0..1s (0 to 0.25 of duration)

//   keyframe 1 occupies t=1..4s (0.25 to 1.0 of duration)

//   keyframe 2 is only reached at t=4s (fill=freeze)

//

// With discrete, the element jumps at keyTime boundaries.
