gtk2-engines-sapwood-dbg 3.1.1.debian.10+0m5-2 (amd64 binary) in ubuntu maverick

 Sapwood is a pixbuf-based 'theme' that allows you to configure the look of
 GTK-using programs. The programs need no modifications to use themes; the
 support is built into GTK+.
 .
 The engine is similar to the pixbuf engine, but uses client-server design
 and pixmaps rather than pixbufs. It is faster and more memory efficient than
 the pixbuf engine, but doesn't do scaling or gradients.
 .
 This package contains symbol tables for debugging.
