*
* $Log: StylesheetFactory.java,v $
* Revision 1.2 2007/05/16 22:27:14 peterbrant
* Only load default stylesheet once
*
* Revision 1.1 2005/06/23 17:03:42 tobega
* css now independent of DOM
*
* Revision 1.21 2005/06/22 23:48:41 tobega
* Refactored the css package to allow a clean separation from the core.
*
* Revision 1.20 2005/06/16 12:59:23 pdoubleya
* Cleaned up support for reloading documents.
*
* Revision 1.19 2005/06/16 11:29:12 pdoubleya
* First cut support for reload page, flushes inline stylesheets.
*
* Revision 1.18 2005/06/16 07:24:46 tobega
* Fixed background image bug.
* Caching images in browser.
* Enhanced LinkListener.
* Some house-cleaning, playing with Idea's code inspection utility.
*
* Revision 1.17 2005/06/15 11:53:45 tobega
* Changed UserAgentCallback to getInputStream instead of getReader. Fixed up some consequences of previous change.
*
* Revision 1.16 2005/06/01 21:36:36 tobega
* Got image scaling working, and did some refactoring along the way
*
* Revision 1.15 2005/03/24 23:17:58 pdoubleya
* Added debug dump on bad CSS input.
*
* Revision 1.14 2005/02/03 23:08:26 pdoubleya
* .
*
* Revision 1.13 2005/01/29 20:19:21 pdoubleya
* Clean/reformat code. Removed commented blocks, checked copyright.
*
* Revision 1.12 2005/01/10 23:24:46 tobega
* Created image cache
*
* Revision 1.11 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 1.10 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 1.9 2004/11/30 23:47:57 tobega
* At-media rules should now work (not tested). Also fixed at-import rules, which got broken at previous modification.
*
* Revision 1.8 2004/11/29 23:25:40 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 1.7 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 1.6 2004/11/15 22:22:08 tobega
* Now handles @import stylesheets
*
* Revision 1.5 2004/11/15 20:06:31 tobega
* Should now handle @import stylesheets, at least those with absolute urls
*
* Revision 1.4 2004/11/15 19:46:14 tobega
* Refactoring in preparation for handling @import stylesheets
*
* Revision 1.3 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.
