Pardon me replying to my own post.....
The above may help with LPub showing the right portion of a large mode, but it
doesn't help with cropping the image size to contain what has changed, which I
think would have a significant impact on building instruction size. LEGO does
occasionally show cropped portions of whole model images, but they don't do that
as a general rule. But then again, they don't generally sell 25 foot tall Sears
towers.
LPub already has a mechanism for identifying where callouts are added to a model
so it can place the arrows from the callout to the center of the callout usage.
I suppose it could do a similar thing for "parts added in this step" and crop
the image to contain those. I'm pretty sure that would not be the default
behavior though. Egads, more features.
I gotta get through the backlog of bugs first.
