Direct Known Subclasses:

AbsoluteCrossoverScalingControl
```
public class CrossoverScalingControl
extends java.lang.Object
implements ScalingControl
```
A scaling control that has a crossover point. When the overall scale of the view and model is less than the crossover point, the scaling is applied to the view's transform and the graph nodes, labels, etc grow smaller. This preserves the overall shape of the graph. When the scale is larger than the crossover, the scaling is applied to the graph layout. The graph spreads out, but the vertices and labels grow no larger than their original size.
