◆ ED_undosys_stack_memfile_id_changed_tag()

void ED_undosys_stack_memfile_id_changed_tag	(	UndoStack *	ustack,
		ID *	id
	)

If the last undo step is a memfile one, find the first MemFileChunk matching given ID (using its session UUID), and tag it as "changed in the future".

Since non-memfile undo-steps cannot automatically set this flag in the previous step as done with memfile ones, this has to be called manually by relevant undo code.

Note: Only current known case for this is undoing a switch from Object to Sculpt mode (see T82388).; Calling this ID by ID is not optimal, as it will loop over all MemFile.chunks until it finds the expected one. If this becomes an issue we'll have to add a mapping from session UUID to first MemFileChunk in MemFile itself (currently we only do that in MemFileWriteData when writing a new step).

Ideally we wouldn't need to export global undo internals, there are some cases where it's needed though.
