"closed"
You can draw straight lines while you press Shift and clic in a blank
space inside the canvas.
You can write a decimal number to set the measure. It has a bug which
will be fixed in the next nightly release.
Fixed a compatibility bug which it doesn't work in firefox, still there
is a bug in IE version about cleaning the shape.

When you close a shape, you can add the measure of the last side.
