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

[Nicolás Papagna Maldonado]

Hi Luciano!

I've done an experiment about that in the past, inspired by a React tool
that does a similar thing.

The idea is to install a method wrapper on the #drawOn: method you want to
profile and gather metrics there (IIRC I did FPS, P90, P50, etc).
I also drew a box around the profiled morph and showed these metrics live,
too. IIRC I wrapped the #postDrawOn: method as well to display that.

Once you have the wrappers installed is easy to collect the info or do
whatever you want.

Here's a link to a Cuis Slack chat
<https://ba-st.slack.com/archives/CH47P6ZMK/p1682798005359369> where I
showed it (in spanish).

Cheers,
Nico PM
