All position and rotation keyframes are now preserved, even those similar to the previous keyframe. This is required for truthful playback in engine.

Anim exported as DMX, then reimported to blender to view the keyframes.
Before:
image_before

After:
image_after

All position and rotation keyframes are now emitted, even those similar
to the previous keyframe.

Kylul mentioned their Engineer Animation Mod Pack has jitter issues in-game. They noted they could not see them in Blender. This would explain it. Awesome Fix. Hope it gets implemented soon :)

I've put together a release downstream, which implements this fix.
