  Class GradientFillMorph is obsolete. For getting gradient fills use a BorderedMorph with an appropriate fill style, e.g.,
 
  | morph fs |
+ morph := BorderedMorph new.
+ fs := GradientFillStyle ramp: {0.0 -> Color red. 1.0 -> Color green}.
- morph _ BorderedMorph new.
- fs _ GradientFillStyle ramp: {0.0 -> Color red. 1.0 -> Color green}.
  fs origin: morph bounds center.
  fs direction: (morph bounds width // 2) @ 0.
  fs radial: true.
  morph fillStyle: fs.
  World primaryHand attachMorph: morph.
 
  Here's the old (obsolete) comment:
  GradientFills cache an array of bitpatterns for the colors across their rectangle.  It costs a bit of space, but makes display fast enough to eschew the use of a bitmap.  The array must be recomputed whenever the colors, dimensions or display depth change.!

  Object subclass: #Command
  instanceVariableNames: 'phase cmdWording undoTarget undoSelector undoArguments redoTarget redoSelector redoArguments parameters'
  classVariableNames: ''

  An object representing an undoable command to be done in the environment.
 
  Structure:
  phase indicates whether the cmd is current in undone or redone mode
    cmdWording The wording of the command (used in arming the "undo"/"redo" menu items
    parameters an IdentityDictionary /NOT USED/
  undoTarget Receiver, selector and arguments to accomplish undo
  undoSelector
  undoArguments
  redoTarget Receiver, selector and arguments to accomplish redo
  redoSelector
  redoArguments
 
  To use this, for any command you wish to use, you
  * Create an instance of Command, as follows...
+ cmd := Command new cmdWording: 'resizing'.
- cmd _ Command new cmdWording: 'resizing'.
  * Give the the command undo state and redo state, as follows...
  cmd undoTarget: target selector: #extent: argument: oldExtent.
  cmd redoTarget: target selector: #extent: argument: newExtent.
  * Send a message of the form
  Command rememberCommand: cmd
 
  LastCommand is the last command that was actually done or undone.
 
  CommandHistory, applicable only when infiniteUndo is set, holds a 'tape' of the complete history of commands, as far back as it's possible to go.
 
  CommandExcursions, also applicable only in the infiniteUndo case, and rather at the fringe even then, holds segments of former CommandHistory that have been lopped off because of variant paths taken.!
