+** Work around bug 493994 in Apache Batik [3]: **
+Apache Batik produces bad PNGs for some SVGs created by Inkscape.
+The workaround is to run the Ant script /org.eclipse.images/build.xml.
+This may modify some SVG files. You should commit these changes.

mvn org.eclipse.images:org.eclipse.images.renderer:render-icons
