@summary Tests that after programmatically moving or resizing a component,
corresponding ComponentEvents are generated only once

IMPORTANT: this test is made manual as some window managers may generate
strange events and that would lead to the test to fail. However, on most
popular platforms (windows, linux w/ KDE or GNOME, solaris w/ CDE or
GNOME) it usually passes successfully.
