surface_v vector

I've been trying to use the surface_v property to make conveyor belts, but I don't think I can. It seems like it's a vector in world space, and because it's applied on a per-shape basis it's impossible to get it to act as I'd want - a constant speed parallel to the surface it's applied to.

As far as I can tell, the component of surface_v that's perpendicular to the surface has no effect, so I'd prefer to have a float surface_speed that works parallel to the surface. That way it could be correctly applied to curved surfaces and so on.

Is there a reason you've chosen to use a vector? And is there any way I could fake it, because I can't see a way to implement a conveyor belt (with two sides and round ends) without this feature.
