Dynamic position/size change and built-in layouts

[Martin Sladecek]

And are you changing the height of the child or it's preferred height?
The height of a managed node is set by the VBox, so you shouldn't 
manipulate with it since if the VBox layout gets dirty, it will reset 
the heigh according to the preferred height.
