Graph-cuts, graph-grid, and the like : z-axis is broken if the range in supercuts is not perfect

Often, @AvivCukierman does something like [100, 201, 10] and this causes the z-axis to look ugly. The best way to fix this is to incorporate logic that does modular arithmetic to fix it :)

Or use numpy arange, and grab the last element as it'll also handle that.
