OK. Seeing this had me a bit worried about performance, but as long
as the browser knows what it's doing, I'm OK with it.
Though in a fractionally zoomed map, with untiled layers, each pan and
zoom would create a unique image request, and the user would be lucky
to have the exact same image request later, so all those cached images
would be wasted. I guess this is a good reason to use defined zoom
levels, and tiled layers when possible...
