That can also be done, with the caveats that:

  . to look at some variable, you will have to add code and recompile
    Emacs
  . if the function(s) in question are invoked frequently when you
    scroll, you will have a lot of output, without a good way of
    knowing which output was caused by which UI gesture

But that doesn't make printf-debugging impossible, so if it's easier
for you, let's try that!

Thanks.
