Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Fix printing of axis grid lines above/below line objects based on "layer". * gl2ps-renderer.cc (draw): For 2D plots, use GL2PS_SIMPLE_SORT for Z-depth sorting rather than GL2PS_NO_SORT which does no calculation whatsoever.
