Also removes all animations but the first one from gltf_frog.gltf
to address the corresponding warning.
Catches some more possible exceptions (out of bounds, optional access)
which might be caused by a broken model to properly log them.
Sets the surprising row-major conventions used here straight.
Renames rotateVect to rotateAndScaleVect:
If the matrix also scales, that is applied as well by the method.
Obsolete rotateVect variants are removed.
The inverseRotateVect method is also renamed accordingly.
Note that this applies the transpose of the product
of the scale and rotation matrices, which inverts just the rotation.
