Is that the right copyright message?

[picksi1, 2014/10/08 13:47:54]

I copied it from smoothness.py, not sure if it should be 2014 though? Does
anyone know?

The header should contain the year in which the file was added (see
http://dev.chromium.org/developers/coding-style#TOC-File-headers).

Done.

Should we say task execution statistics instead of rendering statistics?

Yes! Ctrl-C Ctrl-V error...
