Fixed a memory-leak: The FO tree part of a page-sequence was not released when a page-sequence was finished.
Added a "MemoryEater" debug helper which can replicate page-sequences of a regular FO file using the fo-replicator.xsl. Without the fix a JVM set to the normal 64MB heap size throws an OutOfMemoryError when replicating readme.fo 150 times. With the fix the memory consumption doesn't go above 10MB for the 1350 pages. Note that about one third of the time goes into garbage collection.

By using the getRGB() method we convert all PNG images to sRGB regardless of their original color spaces. So we should also always return the sRGB color space. Otherwise, grayscale PNGs, for example, will not be displayed correctly.
Added support for a 8x8 bayer dither matrix if anyone wants to try that. Currently, 4x4 is hard-coded. The 8x8 might only be an option for larger areas (i.e. not text) but the results didn't look any better when printed.
Attempt to make grayscale patterns look nicer when using PCL commands. The standard PCL shades are very coarse and I replaced them with a simple 4x4 bayer dither pattern defined as a user-defined pattern in PCL.
Current side-effect: Darker gray values will result in almost black output on some printers (at least on mine).
Activating ImageIOImage for reading PNG images in the ImageFactory made some test cases fail. The reason is that the PNGReader cannot extract the image resolution and leaves the default of 72dpi.
Added code to inspect the image metadata for resolution info.
I added the same hack as is already used in PNGImage to force loading the whole image when the image dimensions are requested, i.e. getting the right image size is more important than efficient memory use for now.
The image package needs that redesign sooner or later....
Command-line integration of PDF/X support. Generalized the specifying of PDF profiles (-pdfprofile parameter).
Documentation update for PDF/A.
Documentation for PDF/X.
Fixed two memory-leaks in image handling (ImageFactory and ExternalGraphic). The image cache is finally working properly. Currently implemented without the cleanup thread as done by Batik.
Added ImageIO provider for handling PNG in addition to the internal codec. ImageIO proved to be faster and less memory-intensive for PNGs. ImageIO takes precedence of the internal codec.
Bugzilla #39608:
Let numeric property values without a unit be treated as pixels like in HTML. This fixes certain NullPointerExceptions when no units are specified.
Made FOUserAgent.configure() protected again (not to tempt any users to play with it). Instead improved CommandLineOptions to properly build and adjust the FOUserAgent. Manuel's fix was ok, but I wasn't too comfortable with the public configure() method.
Showing a problem with SVG used inside a basic-link. The size of the link rect is wrong and only spans the area of the nominal line rect. (As reported on fop-users)

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.

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.

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.
