I'm completely confused by that sentence.  You refer to some "image" two =

times, but I fail to see whether it's supposed to be the same image both =

times and, if not, what is the difference between the two.  If it is the =

same image, how would this differ from the new 4.1 plot style "with=20
image"?  Or even from pm3d itself, for that matter?

What is feasible with a single output driver is, ultimately, irrelevant.
For it to make a useful gnuplot feature, it really should be feasible on =

a multitude of drivers.

I'm not sure what "cropping" step you're referring to here, either.
