/**
* This class splits up text into tokens representing a CSS 3 file. It's
* written with a few extra internal states so that it can easily be copy
* and pasted into HTML, PHP, and JSP TokenMakres when it is updated.<p>
*
* This implementation was created using
* <a href="http://www.jflex.de/">JFlex</a> 1.4.1; however, the generated file
* was modified for performance. Memory allocation needs to be almost
* completely removed to be competitive with the handwritten lexers (subclasses
* of <code>AbstractTokenMaker</code>, so this class has been modified so that
* Strings are never allocated (via yytext()), and the scanner never has to
* worry about refilling its buffer (needlessly copying chars around).
* We can achieve this because RText always scans exactly 1 line of tokens at a
* time, and hands the scanner this line as an array of characters (a Segment
* really). Since tokens contain pointers to char arrays instead of Strings
* holding their contents, there is no need for allocating new memory for
* Strings.<p>
*
* The actual algorithm generated for scanning has, of course, not been
* modified.<p>
*
* If you wish to regenerate this file yourself, keep in mind the following:
* <ul>
* <li>The generated CSSTokenMaker.java</code> file will contain 2
* definitions of both <code>zzRefill</code> and <code>yyreset</code>.
* You should hand-delete the second of each definition (the ones
* generated by the lexer), as these generated methods modify the input
* buffer, which we'll never have to do.</li>
* <li>You should also change the declaration/definition of zzBuffer to NOT
* be initialized. This is a needless memory allocation for us since we
* will be pointing the array somewhere else anyway.</li>
* <li>You should NOT call <code>yylex()</code> on the generated scanner
* directly; rather, you should use <code>getTokenList</code> as you would
* with any other <code>TokenMaker</code> instance.</li>
* </ul>
