Make a large image and group it a smaller size so that it scrolls. Then edit
the group, adding objects where you want them.

I made a metamap set that scrolls via mousemove techniques. I could have
added scrollbars to the group, but I didn't want them in that case.

The large map is 3ft x 4 ft. That's waaay offscreen and even waaay waaaaay
larger than the window it's in. As such, it's a big file, and not practical
for emailing.

However, you're in luck. I made a demo that shows how it works, same basic
scripts. I added a couple of buttons just now by editing the group.

This I can send if you want to take a look. It scrolls via the scrollbars
_or_ the mousemove routine, which backscrolls the scrollbars correctly at
the same time.

Might give you some ideas. OK to send it to you offlist?
