Amy, can you add an event that signals the end of the user moving a point? Then, pass the bug back to me.

I've added EndInteractionEvent to the vtkTransferFunctionViewer. This event is fired when you finish moving a transfer function node.

The 3D view is now only updated when the point move is completed instead of at each update. This makes it easier to move points in the transfer function editor. The scalar value and opacity are still updated with each update, so the user can see precisely where the point is.

I didn't add an interactive render to the 3D view. Re-open the bug if the current solution isn't good enough.

This solution is consistent with how tf interactions have happened in the past. It works well enough.
