#1 render tree on level >3

[Matteo Pileggi]

Hi!
I tried to create 3 tree diagram with 2 and 3 level.
The first one is made well, all the leaves are right
paint and the distance each them it's correct.

If I try to paint a 3 level tree diagram it's going down!
Also if I add only a node (leaf) on a previous tree,
the distance, the dimension and the word aren't well
painted

I think there is a bug in a paint algorithm.

In attachment the result of my test
