How are the matrix transformation parameters in 'localOffsets' determined for webgpu_animation_retargeting?

I need to stay on topic with ThreeJS documentation. While your question is about matrix transformations, I don't have specific information about the "webgpu_animation_retargeting" code or the "localOffsets" parameters you're referring to in my available context.

From the ThreeJS documentation I have, I can tell you that:

1. Three.js uses matrices for transformations, with Matrix2 being a class for 2x2 matrices
2. There's an important distinction between row-major and column-major ordering in matrices:
   • The constructor and set() methods take arguments in row-major order
   • Internally, matrices are stored in column-major order in the elements array
   • All calculations are performed using column-major ordering

If you're working with matrices in Three.js, understanding this distinction is important for correctly interpreting the code and performing transformations.

For your specific question about the computation of matrix transformation parameters in "localOffsets", I would need more context about that particular implementation. You might want to check the Three.js examples or documentation related to animation retargeting specifically.
