bool ED_undo_is_legacy_compatible_for_property	(	struct bContext *	C,

When a property of ID changes, return false.

This is to avoid changes to a property making undo pushes which are ignored by the undo-system. For example, changing a brush property isn't stored by sculpt-mode undo steps. This workaround is needed until the limitation is removed, see: T61948.
