/**
* <code>MacMetalJLabel</code> shows that under certain circumstances that
* apply only to the Macintosh, JLabels can miscalculate their sizes so that
* many of them are not full drawn and instead end with an ellipsis (...).
* Other, similar components (e.g. JCheckBox) are also affected.
*
* <p>This bug only occurs with the Metal LnF *and* with antialiasing enabled.
* Thus, to see the bug, this program must be run as follows:
<pre>java -Dswing.defaultlaf=javax.swing.plaf.metal.MetalLookAndFeel -Dapple.awt.antialiasing=on MacMetalJLabel</pre>
*
* <p>The bug occurs with a variety of layout managers.
* Those that are most susceptible (e.g. BoxLayout, FlowLayout) are the ones
* that allow all components to be their preferred size and do not force them
* to be larger.
* GridLayout, on the other hand, forces everything to be as large as the largest
* component. Thus, only the string "mainchain" is initially clipped in those
* layouts, and stretching the window also stretches the JLabels so that none
* of them end up clipped.
*
* <p>I can temporarily work around this bug by overriding JLabel (or JCheckBox, etc.)
* and increasing its preferred size by 1 pixel.
