示例1: ConvertLinearToCurvedSpaceGlobal
// QQQ new utility 2-25-04 -- may replace inline code elsewhere
//
// Given a location in this vehicle's linear local space, convert it into
// the curved space defined by the vehicle's current path curvature. For
// example, forward() gets mapped on a point 1 unit along the circle
// centered on the current center of curvature and passing through the
// vehicle's position().
//
