Each position axis not being processed individually when compressing animation with Keyframe Reduction

Animation

-

To reproduce:
1. Create new unity project, import user's FBX file
2. Open Animation window, in Project window, expand imported FBX file
3. In expanded FBX, click the animation, and then the parent file again
4. In Inspector window, change around the position error property

Expected: identical keyframes are deleted even with minimal position error
Actual: keyframes are only deleted with a huge allowed position error

Reproduced in: 5.5.4p2, 5.6.3f1, 2017.1.0p3, 2017.2.0b6, 2017.3.0a3

Note: keyframes either get deleted on all axis or on none of the axis

  1. Resolution Note:

    Keyframe reduction on position is expressed as an acceptable error percentage. The default is set to 0.5%. This means that for a key to be removed, the error must be less than 0.5% of the key's value.

    Contrary to what is claimed in the bug report, there is actual variation on the values, but they are all so small that any variation is a big relative variation.

    If you want very small values to be ignored, then you need to filter them out before importing them to Unity
