   * Apply patch from Paul Tagliamonte, updating the Joy pictures to use
     the correct brand; the Debian logo is now DFSG free.
+  * When SPLASH_PNG is set, search for a matching SPLASH_SVG; if it's
+    found, call rsvg-convert to generate the PNG file. Clean those on
+    reallyclean. Add librsvg2-bin build-dep for rsvg-convert, restricted
+    to any-{amd64,i386} (splash is used on x86, kfreebsd, and hurd).
