XShow and XDisplay XDE require VISUALIZATION for correct work.
In some scenario DRAWEXE can generate a duplicates of the internal static singletons.
This means each dynamic library will have their own instance of the static singleton.

This will ensure that the XDE plugin is loaded only once and that the correct instance is used.
Originally issue is reproduced only Linux with dlopen with "RTLD_LAZY".
Can be resolved additionally adding "RTLD_LAZY | RTLD_GLOBAL" for dlopen
- Extended command Close with an option -silent
- Extended command Close to handle */-ALL for closing ALL document
- Replaced catch {Close D} by Close D -silent in tests
