- to modify the curve as you want. You can create several nodes on
- the curve.

- You can have only two curves on the grid, one for the so named
- "upper" border and the other for the so named "lower" border. You
- can activate one of them by checking the <span class="emphasis"><em>Upper</em></span>
- or <span class="emphasis"><em>Lower</em></span> radio button.
