I believe that the dbfawk stuff can give you this same sort of
granularity (or darn close), but you of course end up having Xastir
look through all the features in the file to determine this, which
can be a big waste of time.  It might look the same but take 10
times longer to display.

If you want the maximum speed for rendering lots of map data at
once, it sounds like you're headed down the correct path.  For
maximum flexibility with minimum hassle, custom dbfawk files are the
way to go.
