…ly invisible - added method 'TBaseVirtualTree.GetTopInvisibleParent' to retrieve the topmost node of an effectively invisible subtree - the resulting node can be invisible by lacking the 'vsVisible'-flag on its own or having its parent lacking the 'vsExpanded' flag - all of its sub-nodes can be considered effectively invisible - all of its ancestor-nodes can be considered to be effectively visible - 'nil' is returned if all nodes from 'Node' up to 'FRoot' are effectively visible
…it]' completely to ensure a node cannot be returned as its own next or previous node - updated methods 'TBaseVirtualTree.GetNextVisible' and 'TBaseVirtualTree.GetNextVisibleNoInit' as well as 'TBaseVirtualTree.GetPreviousVisible' and 'TBaseVirtualTree.GetPreviousVisibleNoInit' to harmonize the determination of a next or previous visible node - used method 'TBaseVirtualTree.GetTopInvisibleParent' to optimize the search by skipping effectively non-visible subtrees as a whole independent from 'ChildrenAbove' mode - applied the condition to force searching for another node from 'TBaseVirtualTree.GetNextVisible' and 'TBaseVirtualTree.GetNextVisibleNoInit' to 'TBaseVirtualTree.GetPreviousVisible' and 'TBaseVirtualTree.GetPreviousVisibleNoInit' - extended that condition to force searching for another node when the current node is known to be in an effectively non-visible subtree - thus, the input node cannot be returned as its own next/previous visible node, which is ensured with an assertion at the end of each method - note that the usage of other methods obscuring the traversal algorithm, such as 'GetVisibleParent', 'GetFirstVisible', 'GetLastVisible', 'GetPreviousSibling', etc. is avoided
