Approximation for the minimal allowed size for the boxes.
The default value is 10.
This property has effect if isPreventSmallBoxes() is set to true only. This is only the approximation of the size in pixels, it is NOT an exact value. "Size" means linear dimension of the box, e.g. width and height.

Flag determining if small boxes should be enlarged to ensure some visible area (true) or not (false).
The default value is false.
Sometimes for the trees with a huge difference in weights across children, some boxes may appear too small. For example, if you create a tree with two nodes weighted 99.9 and 0.1, then the first one will be very large, and the second one will barely be visible. This might look ugly. To prevent this, you can set this flag to true and tune the getMinimalSizeApproximation() property to achieve nicer results.
