    RMvisMap indices (input).
 RMvisMap *vmap - a handle to an RMvisMap object (input).
 int axis_offset_flag - an RMenum specifying in which axis to
    offset.  Must be one of RMV_XAXIS_OFFSET, RMV_YAXIS_OFFSET, or
    RMV_ZAXIS_OFFSET (input).
 int mesh_dims[2] - int specifying the mesh dimension (input).
 RMnode *node - a handle to an RMnode (modified).
