annotate nodejs/svg.js @ 888:143ac14c3ce9 abs_n_rel_center

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Set opacity for a path. You can not set opacity on a shape of MadButterfly, but you can set opacity for a coord. We add an additional coord to contain a path, and set opacity on the containing coord.
