/**
* The <code>javax.swing.text.View</code> object used by {@link RSyntaxTextArea}
* when word wrap is disabled. It implements syntax highlighting for
* programming languages using the colors and font styles specified by the
* <code>RSyntaxTextArea</code>.<p>
*
* <p>
* You don't really have to do anything to use this class, as
* {@link RSyntaxTextAreaUI} automatically sets the text area's view to be
* an instance of this class if word wrap is disabled.<p>
*
* <p>
* The tokens that specify how to paint the syntax-highlighted text are gleaned
* from the text area's {@link RSyntaxDocument}.
