applying Jaime's rotation

[stephengold]

At commit: 4cd137d
To reproduce: 4, 1, Apply
Expected: no change in model appearance
Got: light brown zebra stripes on Jaime
Hypothesis: incorrect rotation of tangents and/or normals

Omitting the MyMesh.rotateTangentBuffer() invocations in SelectedSpatial.applyTransform() seems to solve this issue.

However, it reveals that the bone transforms in the animations need to be transformed as well. Leave this open for now.

Jaime is a particularly tricky case, because the rotation occurs between the SkeletonControl and the Mesh. Perhaps Maud should test for this condition and refuse to apply the transform.
