Update on libxalan2-java to main

[Wolfgang Baer <WBaer@gmx.de>]

Hi all,

there is a short update on xalan2.

I had success building xalan2 including javadoc and
other docs with gij-3.4/kaffe and gjdoc 0.7.4

This setup needs a rather hacked build script and rules
file and works ONLY on the users machine. I have not
succeeded to built it in a chroot due to missing
java.awt.headless implementation in free vm's.

Another setup with the new libant1.6-java and kaffe does not
need the gij-3.4 any longer and also no hacked build script
or rules file.

However this setup fails as it needs a Graphics2D object
for transformation of the documentation with:

[java] [Xalan2Processor] Applying XSL sheet 
"sbk:/style/stylesheets/context2label.xsl"
[java] java.lang.Error: Grahics2D not implemented. Cairo was not found 
or disabled at configure time
[java] at gnu.java.awt.peer.gtk.GdkGraphicsEnvironment.createGraphics 
(GdkGraphicsEnvironment.java:80)
[java] at java.awt.image.BufferedImage.createGraphics 
(BufferedImage.java:293)

...

I tried also with a local built kaffe with the cairo Graphics2D
implementation. This fails with the following exception:

[java] [StyleBook] Caught java.lang.ClassCastException
[java] java.lang.ClassCastException: can't cast 
`java/awt/image/BufferedImage' to `gnu/java/awt/peer/gtk/GtkImage'
