I've actually done this: Create an object graphics hirearcy, then use
VIEWPLANE_RECT to scan through chunks. It turns out that routines like
WRITE_PNG don't have the same dimensional limits as IDLgrBuffer does,
so the image can be reassembled in IDL before using something like
write_png to output a file.

I'll dig up the code I used for this to make sure that what I
described is actually what I did.
