+             * This has to handle both when a user draws on the terrain *and* when a user selects 
+             * a selection of AABB on terrain and applies whatever routine the client requests
+             * There's something currently wrong with the brushsize --> size conversion..   however
+             * it's workable..  just unpredictable.
+             * 
+             * North is always higher and East is always higher
+             * in the AABB representation
+             * 
+             * Therefore what we're doing is looping from south to north and west to east
+             * and applying the associated algorithm with the brush.
+             * 
+             * This works good on the fast ones, but things like smooth take 12 seconds a single click..  
+             * for now, smooth won't be 'selectionated'
+             * 
+             * If the user draws instead of selects, north will = south, and east will = west.
+             * if the user selects, then the selection is inclusive
+             * it'll always affect at least one point on the heightmap.
+             * 
+             *  that means we use the <= operator
+             * 
+             * Again, libTerrain is yx instead of xy..  so, it's reflected in the function calls
