Subject: * Terrain modification more robust, uses area sizes matching those
 employed by the client display. * Terrain tools now account for the duration
 the cursor was held for. * Terrain tools now support new brushes (completing
 the common set) ** Smooth brush ** Flatten brush ** Revert brush ** Noise
 brush
