As someone currently using their own touchscreen controller with GTK, I'm
going to have to argue that this is not always the case.  My system can
execute programmable code on both "press" and "released", which comes in
handy for my customer who want to say, hold down the button to issue a
"start jog" command to a serial motion controller.  When they release, I
send the "stop job" command.

Add a bit of logic to compensate for the fact that my Xfbdev server seems to
be able to hit "released" without "press", make the buttons big enough for
finger hitting, and get a touchscreen that Doesn't Suck (I like Gunze better
that Microtouch, for one -- more 'solid' feel.)
