Well, the Tcl/Tk version has the advantage that you aren't limited by
the size of a monitor window. You can already scroll around the
current region; the issue is whether you need to be able to work on a
region which is larger than that which can reasonably be loaded at any
one time.

Well, you can't actually *zoom*, as you're editing individual cells
(the original d.rast.edit generates an error if the region resolution
doesn't match the raster's native resolution). But it looks like I
need to add a "pan" tool.
