I will have to investigate this further on native then (I'll look into making a fake driver that implements Arc and MoveTo but not ArcTo, call ArcTo on that driver and see what happens).
I don't know whether this is a valid case, but what I'm thinking of is a pre-Win2000 GDI driver (have to double check that that is a possibility...) that implements Arc but not ArcTo since ArcTo was only added in Win2000.
The GDI driver interface is purely Wine internal, it has nothing to do with Windows drivers.
