XML Graphics Commons 1.0 replaced with a SVN snapshot (containing the XMP framework).
Reworked the XMP support for PDF to use the XMP framework from XML Graphics Commons.
XMP metadata embedded in fo:declarations is now properly handled. Its values are copied to the Info object according to the rules from PDF/A-1.
Metadata values from the user agent (title, author etc.) are properly merged with metadata from the XSL-FO document. UserAgent metadata overrides FO metadata.
Note: This is useful and active even if you don't activate PDF/A support.

Added initial support for PDF/X-3:2003 (ISO 15930-6:2003(E)).
Fixed bugs in PDF/A support: Transparency is now switched off and the CIDSet object is generated for CID fonts.
PDF/A and PDF/X are now "profiles" (see PDFProfile) which are used to control the allowed, required and forbidden features in PDF. PDF/A-1b and PDF/X-3:2003 can both be activated simultaneously as they are compatible.
For PDF/X, color handling has been improved a little (PDFColorSpace is now an interface, the old PDFColorSpace is now PDFDeviceColorSpace) and most importantly, the "DefaultRGB" color space is now mapped to the sRGB color space (for all colors in DeviceRGB) which ensures that all sRGB colors from XSL-FO are also sRGB colors in PDF which wasn't necessarily the case before.
For PDF/X, added support for a custom, non-sRGB output profile because PDF/X requires a "Output Device Profile" (which sRGB is not).
ICC profiles are now shared/cached among images.
Added support for fox:conversion-mode="bitmap" in the PDFRenderer to handle SVGs with transparency when transparency is forbidden (PDF/X and PDF/A). Only drawback: the image is not combined with the background. An opaque bitmap with a white background is generated.

Added region-body_display-align to demonstrate the default behaviour for adjustable spaces when display-align is set to "auto".
Reactivated proprietary display-align="distribute" so a block-container can cause its content to be "justified" in the reference area if it's large enough and the adjustable elements (min/opt/max) allow for it. I may be misusing the original intended behaviour of "distribute" but for block-container this seemed suitable since it's destined to produce only one viewport/reference pair if possible. Test added that demonstrates the proprietary value on block-container. Note: on normal region-body elements, display-align="distribute" has currently no effect since the code did not evolve with the changes in the layout engine.

Improved accuracy of font size selection. The font size is not rounded down to the next integer point value anymore. (Java2D renderers profit from that one, too)
PCL Renderer:
Found a use case for that Java2D ascent value (which I call MaxAscent). It is used for painting text as bitmaps and to make sure the image the text is painted on is big enough if the font ascends beyond the em box. For non-Java2D fonts, MaxAscent is the same as ascent.
Added a check that lets text painting fall back to bitmaps if there are characters that are not in the ISO-8859-1 encoding. This also enables Symbol and ZapfDingbats fonts.
A "text-rendering" setting allows to disable PCL text painting in case the mix of PCL and bitmap text painting should result in unwelcome output. Note: the bitmap rendering is relatively slow (many small bitmaps). In the end we might end up rendering using a BitmapRenderer and only wrapping the whole thing in PCL (much like the Windows PCL drivers do). This would be faster than creating many small bitmaps.

Several bug fixes in PCLRenderer (border painting mostly).
Option in AbstractGraphics2DAdapter to work with or without alpha.
Text Setup changed to the Java2D model. Custom font painting is now done through Java2D as bitmaps for all fonts which are not supported by the pre-defined set. This was done as a shortcut for full-fledged TrueType support which seems to be a little complicated in PCL. BTW, Microsoft PCL printer drivers do the same, i.e. paint text as bitmaps.
Image printing refined, but my attempt at handling bitmasked images (transparency) didn't work out. While the previewers did the expected thing, the printer hardware flat-out ignored it, so it's disabled now.

fox:disable-clipping on the i-f-o or e-g can be used to perform more painting operations natively in the HP GL/2 space. Since HP GL/2 provides only limited clipping functionality (which is not supported, yet) and the PCLGraphics2D fails with an UnsupportedException if it encounters an unsupported painting operation, every SVG graphic ends up being painted as a bitmap. This setting can help avoid that. Of course, I have yet to implement the IW (InputWindow, used for rectangular clipping) command.
