R: [GRASS-user] query multiple raster

[Michael Barton]

It would be nice, but a lot of work. It would take a major rewrite of the
raster layer code because of the way the layer information is gathered.

However, the new wxPython GUI DOES do multi-layer querying automatically. In
fact, it queries both rasters and vectors at the same time.
