[Bf-committers] patch for tech mode

[Kenneth Styrberg]

To whom it might concern!

I added a scale variable to the draw edge length and area for my own 
project, I'd like to share it to anyone interested.

I maybe did some shortcuts to get the scale variable to the drawobject 
function, so please check O:-)
