Support for reporting changes for constrained integer properties. This method can be called
before a constrained property will be changed and it will send the appropriate
PropertyChangeEvent to any registered VetoableChangeListeners.

@param propertyName the property whose value has changed
@param oldValue the property's previous value
@param newValue the property's new value
@throws PropertyVetoException if a constrained property change is rejected
