  * i.emissivity: new

+ * i.fft and i.ifft: In GRASS 6.x, the only operation which can be performed upon the FFT data is a binary mask; a given component can be included or excluded, but not scaled. In GRASS 7.0, the frequency coefficients are saved as raster maps, so they can be manipulated with e.g. r.mapcalc. The main constraint is that both i.fft and i.ifft require the data to fit into memory. Eliminating this requirement boils down to transposing a large array efficiently. * i.latlong: new
