<p>This test checks our support for window sizing and positioning.</p>
<p>To test: Click each button below. Check to make sure that the window it opens has the specified attributes.
   Also check for a series of 'PASS' messages below the button.</p>
<p style="color:red">NOTE: Make sure to test at magnified resolutions.</p>
<p>To test @ 2X resolution:</p>
<ol>
<li>Open Quartz Debug (/Developer/Applications/Performance Tools).</li>
<li>Select Tools -> Show User Interface Resolution.</li>
<li>Set the resolution to 2.0.</li>
<li>Restart Safari.</li>
</ol>
