          icon - icon editor


          Icon is a pixel-level editor for textures and small bitmaps.
          Icon's layer has in the lower right a magnified grid, where
          each square represents a pixel, and in the upper left the
          image in real size.  Editing is done on the magnified grid.
          Pixels can be turned black by pressing the left mouse but-
          ton, and can be turned white by pressing the middle button.
          Many of the command icons require a rectangle to be swept;
          this is done either by the middle button (which supplies a
          fixed 16×16 rectangle) or by the right button (for rectan-
          gles of any size).
