/**
* A distinct rendering area of a Swing component. A component may
* support one or more regions. Specific component regions are defined
* by the typesafe enumeration in this class.
* <p>
* Regions are typically used as a way to identify the <code>Component</code>s
* and areas a particular style is to apply to. Synth's file format allows you
* to bind styles based on the name of a <code>Region</code>.
* The name is derived from the field name of the constant:
* <ol>
* <li>Map all characters to lowercase.
* <li>Map the first character to uppercase.
* <li>Map the first character after underscores to uppercase.
* <li>Remove all underscores.
* </ol>
* For example, to identify the <code>SPLIT_PANE</code>
* <code>Region</code> you would use <code>SplitPane</code>.
* The following shows a custom <code>SynthStyleFactory</code>
* that returns a specific style for split panes:
* <pre>
* public SynthStyle getStyle(JComponent c, Region id) {
* if (id == Region.SPLIT_PANE) {
* return splitPaneStyle;
* }
* ...
* }
* </pre>
* The following <a href="doc-files/synthFileFormat.html">xml</a>
* accomplishes the same thing:
* <pre>
* <style id="splitPaneStyle">
* ...
* </style>
* <bind style="splitPaneStyle" type="region" key="SplitPane"/>
* </pre>
