[Cuis-dev] benchmarking and profiling morph's drawOn:

[Luciano Notarfrancesco]

Sounds useful, but I couldn’t watch the video (wouldnt start playing). Is
there a package for that?
Also, the stock time profile doesn’t always work well, sometimes it seems
to think that time is spent on the wrong method (looks like maybe off by
one line, or perhaps just not accurate enough), I guess with method
wrappers it could work better.
