Flip Animation is inexact when keyframes don't fit Snapping

[Cub0use]

What are you trying to do, and what do you expect to happen?

Using Flip Animation to copy and offset keyframes to a symmetrical group.

What happens instead?

• The starting/ending keyframes are doubled at 1 step offset from one another.

• There should be a created keyframe at the end of the flipped channel, the same as at timestamp 0 (when there isn't an original one at exactly half the animation length)

• The keyframes in the middle of the animation are not placed precisely at + half the animation length (because they respect the animation's Snapping value).

When I double the snapping to 50, the flipped keyframes can get a timestamp offset by exactly half the animation length, and the issue is not present.

I understand that flipping the keyframes will still be an approximation of the originals when offsetting them, but the two first points are bug material to me.

Perhaps there should be a tick box in the flip animation tool dialog to double the snapping value, if needed?

I checked in Blockbench 4.11.2, the issues presented in the three bullet points are still present.
