This is done because the Robot sometime ends up clicking on Taskbar or side bar
on Linux and we have had some related issue. Moving to centre helps to avoid
those issues. Also, you just need to call frame.getLocationOnScreen to get the
location along with the frame.bounds to get correct location. But this all is
optional/preferred and it is fine you would like to keep the frame in left top.
