* $Log$
* Revision 1.18 2009/05/09 14:15:14 pdoubleya
* FindBugs: inner class could be static
*
* Revision 1.17 2007/05/20 23:25:33 peterbrant
* Various code cleanups (e.g. remove unused imports)
*
* Patch from Sean Bright
*
* Revision 1.16 2005/10/27 00:09:08 tobega
* Sorted out Context into RenderingContext and LayoutContext
*
* Revision 1.15 2005/06/22 23:48:46 tobega
* Refactored the css package to allow a clean separation from the core.
*
* Revision 1.14 2005/06/16 07:24:53 tobega
* Fixed background image bug.
* Caching images in browser.
* Enhanced LinkListener.
* Some house-cleaning, playing with Idea's code inspection utility.
*
* Revision 1.13 2005/01/29 20:22:17 pdoubleya
* Clean/reformat code. Removed commented blocks, checked copyright.
*
* Revision 1.12 2005/01/25 14:45:54 pdoubleya
* Added support for IdentValue mapping on property declarations. On both CascadedStyle and PropertyDeclaration you can now request the value as an IdentValue, for object-object comparisons. Updated 99% of references that used to get the string value of PD to return the IdentValue instead; remaining cases are for pseudo-elements where the PD content needs to be manipulated as a String.
*
* Revision 1.11 2005/01/24 14:36:35 pdoubleya
* Mass commit, includes: updated for changes to property declaration instantiation, and new use of DerivedValue. Removed any references to older XR... classes (e.g. XRProperty). Cleaned imports.
*
* Revision 1.10 2005/01/03 23:40:40 tobega
* Cleaned out unnecessary styling/matching code. styling/matching is now called during boxing/rendering rather than as a separate stage.
*
* Revision 1.9 2004/12/29 10:39:35 tobega
* Separated current state Context into LayoutContext and the rest into SharedContext.
*
* Revision 1.8 2004/12/12 04:18:58 tobega
* Now the core compiles at least. Now we must make it work right. Table layout is one point that really needs to be looked over
*
* Revision 1.7 2004/12/11 18:18:12 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 1.6 2004/11/07 01:17:56 tobega
* DOMInspector now works with any StyleReference
*
* Revision 1.5 2004/10/28 13:46:33 joshy
* removed dead code
* moved code about specific elements to the layout factory (link and br)
* fixed form rendering bug
*
* Issue number:
* Obtained from:
* Submitted by:
* Reviewed by:
*
* Revision 1.4 2004/10/23 13:51:54 pdoubleya
* Re-formatted using JavaStyle tool.
* Cleaned imports to resolve wildcards except for common packages (java.io, java.util, etc).
* Added CVS log comments at bottom.
*
*
