		eDupli_ID_Flags	duplicate_flags,
		uint	duplicate_options )

Make a deep copy (aka duplicate) of the given collection and all of its children, recursively.

Parameters

dupflag	Controls which sub-data are also duplicated (see eDupli_ID_Flags in DNA_userdef_types.h).
duplicate_options	Additional context information about current duplicate call (e.g. if it's part of a higher-level duplication or not, etc.). (see eLibIDDuplicateFlags in BKE_lib_id.hh).

Warning: By default, this functions will clear all bmain #ID.idnew pointers (BKE_main_id_newptr_and_tag_clear), and take care of post-duplication updates like remapping to new IDs (BKE_libblock_relink_to_newid) and rebuilding of the collection hierarchy information (BKE_main_collection_sync). If LIB_ID_DUPLICATE_IS_SUBPROCESS duplicate option is passed on (typically when duplication is called recursively from another parent duplication operation), the caller is responsible to handle all of these operations.

Note: Caller MUST handle updates of the depsgraph (#DAG_relations_tag_update).
