-----------------------------------------------------+----------------------
 The previous function miscalculates the vertex index along a dimension
 where the grid graph's length is one. The computed vertex index is one
 when it should be zero.
 The offending code is "vertex[dimension_index] = ...
 length(dimension_index) - (distance % length(dimension_index))."
