Subject: Windows of several main functionalities are no longer QDialogs. Fixed
 unexpected behavior. Now visualization window can be closed by sending it a
 close signal. Trying a solution to address the problem that prevents plugins
 from being loaded correctly in Windows if the path contains Chinese
 characters. Not even tried to build in Windows though.
