 * Instances of this class describe operating system fonts.

 * <dl>
 * <dt>height</dt><dd>the height of the font in points</dd>
 * <dt>name</dt><dd>the face name of the font, which may include the foundry</dd>
 * <dt>style</dt><dd>A bitwise combination of NORMAL, ITALIC and BOLD</dd>
 * </dl>
 * If extra, platform-dependent functionality is required:
 * <ul>
 * <li>On <em>Windows</em>, the data member of the <code>FontData</code>
 * corresponds to a Windows <code>LOGFONT</code> structure whose fields
 * may be retrieved and modified.</li>
 * <li>On <em>X</em>, the fields of the <code>FontData</code> correspond
 * to the entries in the font's XLFD name and may be retrieved and modified.
 * </ul>
 * Application code does <em>not</em> need to explicitly release the
 * resources managed by each instance when those instances are no longer
 * required, and thus no <code>dispose()</code> method is provided.
