Fix bug with clone algorihtm.
The clone algo atomatic clone children of a component whith is "fair".
But if the component create it own children in the constuctor or in vsd_init, then some children are cloned twice.
Now we test if a child should cloned or not.
Algo.
if a child as a cloned view with have already a component connected to it (means has member _comp_)
then this comp should not be cloned.
This path should fix the bug with vsd_init, and VSD UI generation process.
But not sure it cover all case ...
Fix a default size for the compoenent
Fix test because of the precision change (vs-util)
