The vis_flags values inheriting icon, icon_state, dir, or ID will now, when applied to a movable atom, make it inherit the "moving" flag of its visual container, so it will display a moving icon state instead of a non-moving one when the containing object is in motion.

VIS_INHERIT_ICON_STATE should use movement states like an overlay does. Or VIS_INHERIT_ID if that'd make more sense. Either way though, it'd be really helpful!
You're right. I think with any of those flags set, movement should be applied.
