Task description: T82645
In terms of Tracking project it should replace MovieTrackingCamera which is too limited in case of code and data reuse.
The main idea of this patch is create LensDistortion ID which contains all camera intrinsics relative to lens distortions only. This allow to animate them, as far as movieclip can be captured using zoom lenses as well as using optical or sensor stabilization, that mean lens intrinsics can be changed per frame. And moreover, compositing node, camera background image/movieclip can reuse this data. Expected that "Movie Distortion" compositing node will have UI representation of lens distortion it used.
For now, it is only draft implementation, missing many important things like actually, MovieTrackingCamera replacement, versioning, ect and less important (correct icon for datablock, ...).
How it should look like:
