Description Andrey Kosyakov 2012-04-11 14:14:56 PDT 
We'd like to spot frames that took long to render even in cases where CPU time usage by nested events was small, so add a contour for overall frame length to frame bars in the vertical overview.
This also requires better scaling logic, so that should we have any irregularly-long frames (i.e. in absence of requestAnimationFrame calls), these do not dwarf the rest of the frames -- so we now scale to no more than 3 * median_frame_length, which causes badly outlying frames to rocket into the sky (right in time for April, 12th).
