Fix for a variety of IK (inverse kinematics) issues on non-puppets not returning nicely to the original pose or not writing fully to the scene, causing a one frame glitch when the animation starts or odd situations where the IK keeps choosing different results over multiple frames. Breakages should be fairly uncommon but we have identified a couple.

In this example the IK animation's key frames have springiness applied. This is causing the rig to pull apart. To fix we remove springiness from these key frames.
In this example an idle animation is playing back strangely. This is due to the way the leg is animated. It can be resolved by adding IK to the foot on the off frames.
