The Racket binding for Gtk (or Cocoa or Windows) in `racket/gui`
currently does not report multi-touch events. I agree that multi-touch
events could be supported without too much difficulty, probably, and a
pull request would be welcome --- but there's nothing in place right
now.

Hi all,
Is it possible to detect and handle multi-touch events somehow in the Racket
GUI system? I have tried to look through the documentation, but can only find
mouse- and key events.
As far as I understand, the Racket GUI stuff is based on GTK+, which I believe
is able to handle multi-touch
