This function can be used repeatedly to reverse the number of actions specified by the LAnnAutomation::SetUndoDepth function. When the stack is empty, it returns an error.
There is only one undo depth value per root container. (Subcontainers do not have their own separate values.)
This example reverses the last user action in automation mode.
