[GRASSLIST:344] GIS.m redraws full map after zoom changes despite SQL query in pl ace

[Patton, Eric]

I have a coastline vector map that I'm displaying, and I'm restricting the
display to only one attribute in the gis.m SQL query (CLASS_CODE = 5). I can
only get the query to 'activate' and display a reduced number of vector
objects by turning off the map in the table of contents, erasing and
redrawing the map, then clicking the map back on and re-drawing. Every time
I pan or zoom, the map redraws as if there was no SQL query in place.
