[Tilesathome] Batik jars

[Alan Millar]

I wanted to try Batik rendering instead of Inkscape.  This is on Ubuntu
9.04, which appears to have Batik version 1.7.  I installed libbatik-java,
and changed my tilesAtHome.conf to use BatikAgent instead of Inkscape.

tilesGen.pl crashed with a java stack dump, telling me it could not find
SVGDocument.  I read that SVGDocument.class has moved to a new jar in
Batik 1.7, and it should be in xml-apis-ext.jar

I found this was true in my files.  The only way I found to fix it,
though, was to change the code in lib/SVG/Rasterize/Engine/Batik.pm to add
this jar file name.

I could not find any references to a configuration entry for the Batik jar
list.  Is there one that I just missed, or does the code really need to be
patched?
