This avoids need to do special trickery detecting whether the principal point is to be changed when reloading movie clip. This also allows to transfer the optical center from high-res footage to possibly its lower resolution proxy without manual adjustment. On a user level the difference is that the principal point is exposed in the normalized coordinates: frame center has coordinate of (0, 0), left bottom corner of a frame has coordinate of (-1, -1) and the right top corner has coordinate of (1, 1). Another user-visible change is that there is no more operator for setting the principal point to center: use backspace on the center sliders will reset values to 0 which corresponds to the center. The code implements versioning in both directions, so it should be possible to open file in older Blender versions without loosing configuration. For the Python API there are two ways to access the property: - `tracking.camera.principal_point` which is measured in the normalized space. - `tracking.camera.principal_point_pixels` to access the pixel-space principal point. Both properties are not animatable, so there will by no conflict coming. Differential Revision: https://developer.blender.org/D16573
