Bugfix: Disabled setting widths from AFM since we're using WinAnsiEncoding internally but the AFM delivers the character widths using the font's native encoding which causes problems with some characters.

Reverted revision 603590 which broke the AFP renderer. The other changes after revision 603590 should be preserved as well as possible, including the switch to the new image library.
Adjustments for change in behaviour of the block viewport CTM.
Bugfix: SVG painting is now always done on a color canvas (like for PCL) because Batik cannot handle gradients on a grayscale canvas.
- added full support for keep-with-previous on table-row and in table-cell
- added more testcases for keeps in tables
- assign the right table-row element to grid units that are not on the first row spanned
- slightly re-worked the RowGroupBuilder interface to make it more SAX-like

Added support for reading the OS/2 table's usWeightClass value which supports the same font weight values as we use in XSL-FO.
However, in my tests these values proved to be unreliable (like ExtraBlack fonts returning 400). I just hooked the whole thing in so this work isn't lost if anyone has an idea to make it work. The FontInfoFinder will continue to only use guessed font weights for now.

Bugzilla #44451:
The patch fixes two problems:
- If distinct fonts declare the same font family name, the resulting font mapping is currently arbitrary; now, a name-similarity heuristic is used to prioritize the font mappings.
- "Medium" and "demi" fonts are now recognized as "bold", solving several real-world problems (although this solution may be an oversimplification).
Submitted by: Justus Piater <justus-bulk.at.piater.name>
Patch modified by jeremias:
- Style fixes (tab chars)
- Refined font weight identification: medium -> 500, semi/demi -> 600

Extract original exception in BasePDFTestCase.java. They are normally embedded in a TransformerException and sometimes additionally in a SAXException (depending on the JAXP implementation).

Extracted most of the code in CodePointMapping (generated by XSLT) into a base class for easier maintenance and proper Javadocs.
Deprecated FOP's copy of Glyphs.java.
Took a different approach at handling mapping alternatives for single-byte fonts. The AFM now only lists the main character. Substitution is done through Glyphs.java later in CodePointMapping.
Fixed a problem in Type1FontLoader where the PFM overrides asc/desc/cap/x even though the AFM provides the values. It showed itself because the URW Symbol font has wrong values in the PFM.
Added a note to myself in Type1FontLoader to implement the "Flags" value. The whole thing still seems to work without that part.
Added a glyph name list to the CodePointMapping so we can work with the original list from the AFM. Otherwise, various mapping operations to and from resulted in unwanted mappings (because the mappings are not necessarily 1:1) and in the end the PDF received an incorrect Encoding map. Now there's no such problem anymore.
rowStarted doesn't need to be set in the signalNewRow method. If it is, it will prevent the startTablePart event from being triggered on RowGroupBuilder, in addChildNode. This will lead to a NPE being thrown in CollapsingBorderResolver because it would be improperly set up.

Fix problem with alternate Unicode code point overriding existing better ones in CodePointMapping (ex. a char code for NBSP was used in place of SPACE for non-standard encodings).
Made PFM completely optional if an AFM is available. Widths and Kerning are now also read from the AFM. Fallbacks for missing values are in place. If both AFM and PFM are available, both are used to get the best possible result for certain metrics.

Added support for Type 1 fonts which don't use the AdobeStandardEncoding for PDF and PS output. Details:
Added an Type 1 AFM parser (only basic ltr script fonts are properly supported).
Font loading changed slightly to allow loading an AFM in addition to a PFM.
Added some mapping functionality to CodePointMapping. Now we also build custom CodePointMapping instances from AFM files and use it in SingleByteFonts.
Changed more PDF object classes to make use of the generic PDFDictionary and PDFArray base classes.
Type 1 Fonts with a special encoding now register their encoding in the Encoding value of the font dictionary so the mapping is correct. For PS this isn't necessary as the interpreter just uses the font's default encoding.
Refactored CMap building code to it can also be used outside the PDF context. A CMap can now also be built from a single byte encoding.
Update of XML Graphics Commons snapshot.
Correction/Rectification of changes made in r617989:
* adjustment in ColorUtil to cater for the change
* added check to the color_1.xml testcase, checking for bug 43705
Some minor tweaks:
* added convenience shortcut to PropertyInfo to get to the user agent.
* replaced occurrences to use the shortcut in PropertyParser and RGBColorFunction.
* PropertyParser -> 0% of a length always yields FixedLength.ZERO_FIXED_LENGTH

In addKnuthElementsForBorderPaddingXXX, if the returnlist is a
BlockKnuthSequence, the border and padding should be added to the
first or last paragraph inside it, but it is too late to do that
now. At least, avoid adding it to the bpd sequence.
Removed the 900 penalty mechanism which anyway almost always produced visually bad results. Now the first step for a row is computed so that each cell starting on it can contribute some content.
Used a similar mechanism to replace backtracking: the current row is now allowed to grow as long as there is not enough space on the current page to make the next row fit. The next row is "delayed", so this mechanism is called "row-delaying"
Tweak: modify PercentLength.toString() to return a value that facilitates debugging.
Moved the original code to a getString() implementation, which is now used by the fotree test suite.
Tweak: early percentage resolution by the parser (if the base is known and absolute). Reduces the number of PercentLength instances in favor of cached FixedLengths.

Bugzilla #36391:
Fixed problem with positioning of content when reference-orientation="180" is used. CTM is now correct. It is updated after the height of the content is known. Instead of somehow inverting the element list, I've simply declared this case non-breakable, i.e. I generate one box.
Fixed a few other problems mostly occurring when rotating block-container content by 90 or 270 degrees plus a few remaining auto-height handling problems. This involved switching off some sometimes unwanted side-effects from auto-updating the BPD in some area classes.
Bugzilla 43705:
Fixed a bug when the rgb-icc() function was used before the fo:declarations,

Added very basic parsing for the xml:lang shorthand.
No validation of the specified value, but the language and country
properties now do take the shorthand into account to determine their
value.
Further cleanup/refinement of FixedLength:
* improve consistency in use of the PropertyCache
remove public constructor -> replaced by getInstance() in a handful of classes
* added a sourceResolution parameter to getInstance() and the private
constructor to allow better handling of device-dependent units (px)

Improve breaking for block-container and static-content so there are no more "breaking artifacts" (like additional border lines) in the overflowing part of the content anymore. This is done by removing all breaks from the result list prior to constructing the area tree. The presence of breaks simply indicates that there is an overflow.
