Subject: [PATCH] Andreas Rueckert's patch to fix inline gif image support.
 Does not add compression. I verified that this does not alter the output pdf
 of the example fo files, and it compiles cleanly.

git-svn-id: https://svn.apache.org/repos/asf/xmlgraphics/fop/trunk@193337 13f79535-47bb-0310-9956-ffa450edef68
