+/* 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. */
