- Add support font auto-detection (easier font configuration) including a font cache to speed up the auto-detection process.
- Refactoring of the configuration code: All Avalon configuration stuff is extracted into separate "Configurator" classes.
- Refactoring of the FOURIResolver.
Submitted by: Adrian Cumiskey <fop-dev.at.cumiskey.com>

Changes to the patch by jeremias during the review:
- Font cache simplified (Java object serialization instead of XML), functionality fixed and moved to the fonts.package.
- Relocated default cache file location to user directory.
- Fixed the font configuration for PDFDocumentGraphics2D/PDFTranscoder that got lost with the patch.
- Fixed a problem with having a non-file URL as font base URL.
- Simplified RendererContextInfo stuff to make it easier to understand.
- Fixed handling of Type 1 fonts in auto-detection.
- Reduced verbosity of font-related log output.
- Updated Jakarta Commons IO to version 1.3.1 (the patch depends on it)
- Various javadocs improvements

MimeConstants provides a comprehensive list of MIME types used in Fop.java.

Non-standard, FOP-specific MIME types changed to a uniform pattern: application/X-fop-awt-preview, application/X-fop-print and application/X-fop-areatree.

RendererFactory now supports manual registration and dynamic discovery of Renderers and FOEventHandlers by their MIME types. Instantitation is done using MIME types everywhere.

The RENDER_* constants are mapped to MIME types in Fop.java.

RendererFactory is now an instantiable class whose reference is held by FOUserAgent just like it is done for the XLMHandlers.

Renderers and FOEventHandlers now each have a *Maker class which is a kind of factory class which is used to register a Renderer/FOEventHandler and additionally serves to provide additional information about the thing, such as the MIME types it supports and if the implementation requires an OutputStream.

The command-line gets a new option: -out application/pdf myfile.pdf is the generic way to create an output file. If someone created a WordML output handler and provided the right service resource file he could specify "-out text/xml+msword out.xml". ".out list" lists all MIME types that are available for output.

Renderers can now potionally expose a Graphics2DAdapter which in concert with Graphics2DImagePainter can be used by FOP extensions to paint their content directly using a Graphics2D instance. That makes it possible to avoid a detour via SVG/Batik in certain cases.
