The RendererExistenceEvent.RENDERER_ADD constant defines the value of the type property of the event object for an rendererAdd event.

The properties of the event object have the following values:

Property	Value
`bubbles`	false
`cancelable`	false
`currentTarget`	The Object that defines the event listener that handles the event. For example, if you use `myButton.addEventListener()` to register an event listener, myButton is the value of the `currentTarget`.
`data`	The data item that the renderer is visualizing.
`index`	The data provider index for the renderer that was added.
`renderer`	Contains a reference to the renderer that was added
`target`	The Object that dispatched the event; it is not always the Object listening for the event. Use the `currentTarget` property to always access the Object listening for the event.

RENDERER_REMOVE

The RendererExistenceEvent.RENDERER_REMOVE constant defines the value of the type property of the event object for an rendererRemove event.

The properties of the event object have the following values:

Property	Value
`bubbles`	false
`cancelable`	false
`currentTarget`	The Object that defines the event listener that handles the event. For example, if you use `myButton.addEventListener()` to register an event listener, myButton is the value of the `currentTarget`.
`data`	The data item that the renderer was visualizing.
`index`	The data provider index for the renderer that is being removed.
`renderer`	Contains a reference to the renderer that is about to be removed.
`target`	The Object that dispatched the event; it is not always the Object listening for the event. Use the `currentTarget` property to always access the Object listening for the event.
