Adding a test case that demonstrates a problem with forward references and page-number-citation. The reference's width is adjusted, but not the whole line. Some code in the area tree tries to adjust word- and letter-spacing but it does not seem to be working properly.
Bugfix: Fixed a division by zero problem in TTFReader popping up with arialuni.ttf.
Improved the detection of the capHeight and xHeight font metric values for TrueType fonts. Fonts that contain a version 3.0 PostScript table don't contain unicode glyph names. Without an xHeight value, super- and subscript does not work in FOP.

Fixed various white space (non)removal issues during line building. white-space-treatment is now supported properly especially for the "preserve" case.
Improved JUnit report creation.
Added support for OutputIntent objects in PDF. When PDF/A-1b is activated OutputIntents are created and the sRGB color space is used by default (hardcoded for the moment for lack of better color infrastructure in FOP).
The sRGB color profile from HP (covering sRGB IEC61966-2.1) is now embedded in fop.jar as a resource so the PDF library can embed it. The sRGB profile from the Sun JRE is much bigger. That's why it's not used.
The Gladiator TrueType font (glb12.ttf) has been copied over from Batik and is used to verify PDF/A-1b's conformance checks.
CMYK JPEG image added to test resources so PDF/A-1b color space checks can be performed.
With the color space checks, support for PDF/A-1b is complete to the degree that FOP supports the creation of elements described in ISO 19005-1, except for the case where an embedded XMP packet is used in the fo:declarations element. In this case the metadata is not synchronized with the values in the Info PDF object which could lead to validation errors when checking for PDF/A-1b conformance.
Adding dependency on XML Graphics Commons.
Switching to code in XML Graphics Commons for:
- PSGraphics2D

xmlgraphics-commons-snapshot.jar is a Trunk snapshot built with JDK 1.4.2 from today. It should work under JDK 1.3.1.

Changed PDFText.escapeText() so it doesn't output 7bit ASCII texts in hex mode. This makes it easier to read the PDF in a text editor in most cases.
Fixed the property names for xmp:CreatorTool and xmp:CreateDate (case mistake on my side).
Changed XMP-generation to output the creation date including the time zone to keep Acrobat's preflight check for PDF/A-1b happy. Found that only after more than 3 hours of trial&error.

No stacktrace when encountering problems while building a base URL. It's not necessary and draws too much attention. Instead added the URL to the log message that causes the problem.
Don't validate Base URLs anymore in FOUserAgent because that produces errors (because an URL cannot be built) if a symbolic URI is used which is later resolved through a URIResolver.
Improved support for relative URLs for accessing font resources.
ServletContextURIResolver can now use a base URI that starts with "servlet-context:".

The about attribute must have the "rdf" namespace prefix.
Adobe Acrobat uses an outdated namespace URI for the PDF/A identification, so do the same as Adobe Distiller: write the PDF/A identification twice, once with each namespace URI. Reason: Acrobat is probably the best tool to verify PDF/A conformance right now. jHove covers only part of ISO 19005-1.

Made the loading of user-specified hyphenation patterns usable again and plugged it into URI resolution.
Backwards-compatibility should be maintained.
PatternParser now uses JAXP to get the SAX parser.
Moved the hyphenation pattern cache into a separate class so I can easily plug it into FopFactory later instead of having static variables.
Added serialVersionUID to HyphenationTree. Necessary because the class signature changed.
FOURIResolver does not complain about "file not found" on the log anymore since this should be done by the caller. Until now, this resulted in two log messages about the same problem on the log. "File not found" is still reported but only on level "debug" which might be helpful when tracking down a problem, but at least it's not a "WARNING" anymore.

Certain filter combinations in PDF could lead to invalid PDFs. DecodeParams were not properly handled.
Default filter for XMP metadata set to NullFilter as XMP metadata should always be embedded as clear-text so non-PDF-aware XMP processors can extract the metadata.
Default filter for DCT/JPEG- and CCITT/TIFF-encoded images set to NullFilter because these two compression methods already do a good job. An additional flate filter (as was applied before due to the single default) helps a just little but also adds processing time. If anyone wants to squeeze every possible bit out of the PDF you can use the following in the user configuration:
<filterList type="tiff">
<value>flate</value>
</filterList>
<filterList type="jpeg">
