Hi guys,
I noticed that many people (actually, me too :) ) are a little bit
confused about the geometric functions available in the field calculator.

Many users complain that the help is not clear enough (especially the
examples).
Can we enhance the help of these functions (and maybe also of other
ones) with most clear examples?
Another thing that IMHO would be awesome: can we add some
draws/picture to the help. I don't know if this is technically
possible, but is worth to give a try...

What do you think?

Cheers

Matteo
