Bug when using lowerBound bigger than 0

[lribeiro]

You forgot to add the lowerBound value to ii var on for.

something like: for (var i = 1, ii = ((grid.rows)+(this.settings.lowerBound/2)); i < (ii-this.settings.lowerBound / 2); i = i + 2) {

otherwise, the label will not be correct, due to missing values
