The usage of the lib pointer was cryptic to say the least, it was essentialy used to allow or not local IDs results in the mapping old_id_pointer -> new_id_pointer lookup result. Now: - Explicitely pass a boolean to allow or not local ID as result in lower-level code. - Pass the 'self ID' pointer instead of its library to the whole liblinking code (that was already the case in a few places). Note that naming of the 'self id' pointer is currently very inconsistent throughout the readfile liblink code, this will have to be cleaned up in a separate step later. For now, `self_id` has been chosen for new code as it matches the terminology in lib_query code. The later change can also allow finer handling of lookup on undo, based on how it was re-read (or not), should the need for this arise.

/**
|
|
* A #ViewerPath is a path to data that is viewed/debugged by the user. It is a list of
|
|
* #ViewerPathElem.
|
|
*
|
|
* This is only used for geometry nodes currently. When the user activates a viewer node the
|
|
* corresponding path contains the following elements:
|
|
* - Object the viewer is activated on.
|
|
* - Modifier that contains the corresponding geometry node group.
|
|
* - Node tree path in case the viewer node is in a nested node group.
|
|
* - Viewer node name.
|
|
*
|
|
* The entire path is necessary (instead of just the combination of node group and viewer name),
|
|
* because the same node group may be used in many different places.
|
|
*
|
|
* This file contains basic functions for creating/deleting a #ViewerPath. For more use-case
|
|
* specific functions look in `ED_viewer_path.hh`.
