Nope.  Our code's stupid.  It want's one image and one image only.
The only exception is the geotiff code which is customized to handle
the USGS DRG's, but that's not a remote-file sort of thing anyway.
One or two of our other developers added patches so that the same
code handles DOQQ's fine now too.

Yea, rather like DRG files with megabytes of data per file.
Downloading four of them would suck.  Heck, downloading ONE of them
here on my dial-up would suck.

By the way, the reason I originally wrote the DRG code which joined
maps was because my bowhunting area was very near the intersection
of four quads.  What a stupid reason to contribute to a software
project eh?

I'm really near the border, so I get nervous just discussing this.
Tom could be down here in an hour and a half.  Faster if he's pissed
off.
