Fix the Discontinuity (Euler) Filter

The Discontinuity Filter in Blender fails often it seems when there are 180 degree jumps between consecutive keys. The only solution I found is to manually shift the curves up and down by multiples of 180 degrees to clean out the jumps which you can imagine gets tedious. The Euler filter should be able to identify these jumps and solve them quite easily. This would make a huge difference in Blender animators workflow and drastically speed up the work.

Why not use quaternion ? Animators in general much prefer working with Euler because it allows you to control the curves in the Graph editor with more predictable results tha s, even if we have to manually clean up gimbal issues.
