168 /* Okay, so here's the deal
169 * This has to handle both when a user draws on the terrain *and* when a user selects
170 * a selection of AABB on terrain and applies whatever routine the client requests
171 * There's something currently wrong with the brushsize --> size conversion.. however
172 * it's workable.. just unpredictable.
173 *
174 * North is always higher and East is always higher
175 * in the AABB representation
176 *
177 * Therefore what we're doing is looping from south to north and west to east
178 * and applying the associated algorithm with the brush.
179 *
180 * This works good on the fast ones, but things like smooth take 12 seconds a single click..
181 * for now, smooth won't be 'selectionated'
182 *
183 * If the user draws instead of selects, north will = south, and east will = west.
184 * if the user selects, then the selection is inclusive
185 * it'll always affect at least one point on the heightmap.
186 *
187 * that means we use the <= operator
188 *
189 * Again, libTerrain is yx instead of xy.. so, it's reflected in the function calls
