Glad the lengthy explanation was helpful.

 answer to your question below is probably not--at least I don't know how to
do so. The same processes would apply in any GUI given the GRASS
architecture. Furthermore, interactive zooming--where you must judge the
zooming extent by eye--always has some built in uncertainty. If you think
about drawing programs, the good ones provide an interface to type in
coordinates for high precision--like GRASS does. The only way I can think to
improve the situation is by some kind of snapping to grid cell borders or
vector object nodes. However, this will be difficult as long as what is
displayed on the screen is a graphic output from the GIS. At least I can't
think of how to do this. Maybe a "real" programmer could do so".
