Deleting Controllers
A new "Delete Controller" button has been added to the Track View toolbar that is enabled when one or more delete-able tracks are selected. This method allows a plug-in to indicate to the Track View that one or more of its sub-controllers are delete-able. This provides a way for the user to delete node sub-controllers such as the visibility track, "Image Motion Blur Multiplier", "Object Motion Blur On/Off", etc.
There are two new methods of the Control class to support this. Each has a default implementation so overriding it is optional but developers may wish to do so.
These methods are CanDeleteSubAnim() and DeleteSubAnim(). See Class Control for details.
