ClearAllObjectDisplayModes = ClearObjectDisplayModes

Rhino documentation says: The ClearAllObjectDisplayModes command removes all per-view, per-object display mode overrides.
source: https://docs.mcneel.com/rhino/7/help/en-us/commands/setobjectdisplaymode.htm

This is not true. This command can clear display mode of one object, many objects, or all objects. This means that this command should be renamed to ClearObjectDisplayModes.
