Issue when the armature is scaled

I experienced an issue when the Armature object is scaled to something other than 100% in blender. The model looks and animates fine in blender, but appears bigger or smaller than it should in JME before an animation action is applied. After an animation action is applied to the model, the model assumes the correct size.

It also has a strange impact on DynamicAnimControl (in jbullet and Minie), where the DAC "freezes" into the completely wrong pose when in ragdoll mode.

I was using a Mixamo model with this hierarchy setup:

v Model Root
|   v Armature
|   |   Skinned & Animated Model

I have not tested this problem with other setups.

For more details, view this forum post.

I bypassed this issue by setting Armature scale to 100%, then scaling the model root in JME to make the model appear the same size. Looks and feels the same, but does not experience this issue.

Reproduce the Mixamo hierarchy with a scaled Armature in Blender, then load it in JME and compare its size before and after applying an animation action. Inspect the model-loading and animation path alongside DynamicAnimControl in both jbullet and Minie. Done means the model keeps the correct scale before animation and ragdoll mode no longer freezes in the wrong pose.
