The NotifyChanged event function is executed any time a control is changed on a tool. It executes before the Process event function. Typically the NotifyChanged event is used to adjust the values of controls before they are locked for rendering.
For example, the NotifyChanged function may check to see if a Blur tools Lock X/Y Strength checkbox has been selected. If it has, it could take care of hiding or disabling the Y strength slider, and setting the Y strength to match the X strength.
