Start playing the full animation after setting the ColorValueProvider at the last frame

[Med1D]

I have playOnce animation with context:
playFrom = 0
playTo = 30

When I set the ColorValueProvider with currentFrame = 29.5..<30.0, the layer starts playing the full animation.

In my point of view, there should be trunc or floor. What do you think about it?

Lines 1379 to 1396 in 0f731ab

	// The animation should start playing from the `currentFrame`,
	// if `currentFrame` is included in the time range being played.
	let lowerBoundTime = min(animationContext.playFrom, animationContext.playTo)
	let upperBoundTime = max(animationContext.playFrom, animationContext.playTo)
	if (lowerBoundTime ..< upperBoundTime).contains(round(currentFrame)) {
	// We have to configure this differently depending on the loop mode:
	switch loopMode {
	// When playing exactly once (and not looping), we can just set the
	// `playFrom` time to be the `currentFrame`. Since the animation duration
	// is based on `playFrom` and `playTo`, this automatically truncates the
	// duration (so the animation stops playing at `playFrom`).
	// - Don't do this if the animation is already at that frame
	// (e.g. playing from 100% to 0% when the animation is already at 0%)
	// since that would cause the animation to not play at all.
	case .playOnce:
	if animationContext.playTo != currentFrame {
	animationContext.playFrom = currentFrame
	}

Comparing only whole integer frames makes sense to me. Could you send a PR?

I think trunc probably makes sense. Frame 29.99999 would still be showing frame 29.
