I don't know enough about what a screen object actually is. Are the manuals a
good place to read up on this ?

When I Describe my object, dx says that it will be transformed at rendering.
Does this mean something else other than by display via Image ? I tried
actually piping it through a Render module, but no effect. I will try David's
suggestion of removing the outer screen layer (whatever that is !). This sounds
like it would be directed at the problem that you mention above.

Well, I'm always looking for efficiency since my net is already a burly bear.
The colorbars are especially clunky since they are highly tailored. There are
several colorbars, and I want to put each at different locations within several
separate image frames. I could save at least a full page of net (and probably a
bit of compute time) by not redoing them.
