This test is for testing the bounds of a multimonitor system.
You will see a Frame with several buttons: one marked 'Fill
This Screen' and an additional button for each display on your system.
First, drag the Frame onto each display and click the
'Fill This Screen' button.
The Frame should resize to take up the entire display area
of the screen it is on, and the button text changes to say,
'Get Smaller'.
Click the button again to restore the Frame.
Next, use the 'Move to screen' buttons to move the Frame to
each display and again click the 'Fill This Screen' button.
If the number of 'Move to Screen' buttons is not equals to
the number of screens on your system, the test fails.
If the Frame always correctly resizes to take up ONLY the
entire screen it is on (and not a different screen, or all
screens), the test passes else it fails.""";
