Summary:

Catmull-Rom animation glitches when played by animation controller

Impact:

Makes it hard to rely on catmull rom animations

Repro Steps:

1. Install the attached resource pack
2. Join a world with the resource pack installed
3. Spawn a vanilla sheep
4. Shear the sheep

Observed Results:

When spawning the sheep, the animation plays fine. After shearing it, the animation plays, but some frames of the animation are glitched (see video).

Expected Results:

The animation should play smoothly.

Screenshots/Videos attached: Yes

Regression Builds:

Never worked

Notes:

You might have to watch the animation and/or the video twice to see it, sometimes a frame gets skipped.

Update: We also noticed that the issue doesn't occur if the keyframes are equally spaced.
