GEGL itself contains built in instrumentation that allows breaking
down the time spent in pixel format conversions (babl) as well as the
different nodes of a composition. The small sample gallery at the
website used to be part of an automatic regression testing facility
operated by OSDL called crucible which did nightly builds and
performance/rendering regressions. See
http://www.gegl.org/gallery/clones.txt for examples of how this
infrastructure breaks down processing time.
