Remarks
When assigning new graphics objects to the event arguments, any old graphics object is disposed
of automatically. Likewise, the objects are disposed of when the event arguments are disposed of after
the draw events.
Example
See DrawTreeNodeExtendedEventArgs(Graphics, TreeNode, TreeNodeStates, Rectangle)
for an example of custom drawing the tree nodes.

| NodeParts | This is used to set or get the parts of the node to draw |
| State | This read-only property returns the current state of the tree node to draw |
| StateBounds | This is used to set or get the bounds of the checkbox or state image if it is drawn |

Methods
| Dispose | This implements the Dispose() interface to properly dispose of the event arguments object |
| Dispose(Boolean) | This can be overridden by derived classes to add their own disposal code if necessary |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) |
| Finalize |
This handles garbage collection to ensure proper disposal of the event arguments if not done
explicitly with Dispose.
(Overrides ObjectFinalize) |
| GetHashCode | Serves as the default hash function. (Inherited from Object) |
| GetType | Gets the Type of the current instance. (Inherited from Object) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object) |
| ToString | Returns a string that represents the current object. (Inherited from Object) |
