Returns the direction vector corresponding to the center in (s,t)-space of
the given cell. This is the point at which the cell is divided into four
subcells; it is not necessarily the centroid of the cell in (u,v)-space
or (x,y,z)-space. The point returned by GetCenterRaw is not necessarily
unit length.
