Description

Noticing an issue when keying a camera and then playing back the animation it turns or spins in directions i never intended. Think we need check box for toggling Use Quaternion linear interpolation like we had in Matinee. Looks like it it on by default right now so its picking the shortest distance between keys.

See GIF.

Steps to Reproduce

1. Create a level sequence
2. Add a camera to the level sequence
3. Add transform track and key the rotation zeroed out.
4. Scrub down the timeline
5. Use the rotation widget to rotate -190 on one of its axis and key it
6. Play the animation

Result: Camera rotates going the opposite direction then you intended.
