Library
-------
+ - Performance issue when closing an object
+
+ The slow down is due to the search of the "tag_list" to find
+ out the "corked" status of an object and "uncork" it if so.
+
+ Improve porformance by skipping the search of the "tag_list"
+ if there are no "corked" objects when closing an object.

+ (VC - 2019/2/6)

library).
