/**
* A theme is a set of fonts and colors to use to style RSyntaxTextArea.
* Themes are defined in XML files that are validated against
* <code>themes.dtd</code>. This provides applications and other consumers
* with an easy way to style RSyntaxTextArea without having to use the API.<p>
*
* Sample themes are included in the source tree under the <code>/themes</code>
* folder, but are not a part of the built RSyntaxTextArea jar. Hosting
* applications are free to ship and use these themes as-is, modify them, or
* create their own.<p>
*
* Note that to save a <code>Theme</code> via {@link #save(OutputStream)},
* you must currently create a <code>Theme</code> from a text area wrapped in
* an <code>RTextScrollPane</code>, so that the color information for the
* gutter can be retrieved.
