This will make it easier & cleaner to make custom-built depsgraph (for example for exporting invisible objects to USD or Alembic, see T75936). No functional changes. Reviewed by: sergey Differential Revision: https://developer.blender.org/D8423

/* Optimized builders for dependency graph built from a given set of IDs.
|
|
*
|
|
* General notes:
|
|
*
|
|
* - We pull in all bases if their objects are in the set of IDs. This allows to have proper
|
|
* visibility and other flags assigned to the objects.
|
|
* All other bases (the ones which points to object which is outside of the set of IDs) are
|
|
* completely ignored.
|
|
*
|
|
* - Proxy groups pointing to objects which are outside of the IDs set are also ignored.
|
|
* This way we avoid high-poly character body pulled into the dependency graph when it's coming
|
|
* from a library into an animation file and the dependency graph constructed for a proxy rig. */
