Does binding the procedure argument to setscreen have any effect?  I.e. is

       85 35 {dup mul exch dup mul add 1.0 exch sub} bind setscreen

equivalent in function to

       85 35 {dup mul exch dup mul add 1.0 exch sub} setscreen ?

Does binding the spot function give incorrect results?  If not, it seems
like binding it should give an appreciable savings in speed, since it's
called often.  Or, it could be that the setscreen operator binds it itself,
or some other part of the imaging system does.  In that case, binding it
would have essentially no effect....

Which of the above is correct?  :-)
