 * $Log$
 * Revision 1.17  2007/10/31 23:14:44  peterbrant
 * Add rudimentary support for @font-face rules
 *
 * Revision 1.16  2007/02/20 01:17:11  peterbrant
 * Start CSS parser cleanup
 *
 * Revision 1.15  2007/02/19 14:53:38  peterbrant
 * Integrate new CSS parser
 *
 * Revision 1.14  2006/01/03 23:02:22  peterbrant
 * Remove unused import
 *
 * Revision 1.13  2005/12/30 01:32:41  peterbrant
 * First merge of parts of pagination work
 *
 * Revision 1.12  2005/10/08 17:40:18  tobega
 * Patch from Peter Brant
 *
 * Revision 1.11  2005/06/22 23:48:40  tobega
 * Refactored the css package to allow a clean separation from the core.
 *
 * Revision 1.10  2005/01/29 20:19:21  pdoubleya
 * Clean/reformat code. Removed commented blocks, checked copyright.
 *
 * Revision 1.9  2004/12/11 18:18:07  tobega
 * Still broken, won't even compile at the moment. Working hard to fix it, though. Replace the StyleReference interface with our only concrete implementation, it was a bother changing in two places all the time.
 *
 * Revision 1.8  2004/12/02 19:46:36  tobega
 * Refactored handling of inline styles to fit with StylesheetInfo and media handling (is also now correct if there should be more than one style element)
 *
 * Revision 1.7  2004/11/29 23:25:39  tobega
 * Had to redo thinking about Stylesheets and StylesheetInfos. Now StylesheetInfos are passed around instead of Stylesheets because any Stylesheet should only be linked to its URI. Bonus: the external sheets get lazy-loaded only if needed for the medium.
 *
 * Revision 1.6  2004/11/28 23:29:02  tobega
 * Now handles media on Stylesheets, still need to handle at-media-rules. The media-type should be set in Context.media (set by default to "screen") before calling setContext on StyleReference.
 *
 * Revision 1.5  2004/11/15 22:22:08  tobega
 * Now handles @import stylesheets
 *
 * Revision 1.4  2004/11/15 20:06:31  tobega
 * Should now handle @import stylesheets, at least those with absolute urls
 *
 * Revision 1.3  2004/11/15 19:46:14  tobega
 * Refactoring in preparation for handling @import stylesheets
 *
 * Revision 1.2  2004/11/15 12:42:23  pdoubleya
 * Across this checkin (all may not apply to this particular file)
 * Changed default/package-access members to private.
 * Changed to use XRRuntimeException where appropriate.
 * Began move from System.err.println to std logging.
 * Standard code reformat.
 * Removed some unnecessary SAC member variables that were only used in initialization.
 * CVS log section.
