There is a toolbuilder test that fails if all buttons in the system have gradients. Make it possible to turn off gradients for certain (test) buttons.

  A PluggableButtonMorph is a combination of an indicator for a boolean value stored in its model and an action button. The action of a button is often, but not always, to toggle the boolean value that it shows. Its pluggable selectors are:
 
  getStateSelector fetch a boolean value from the model
  actionSelector invoke this button's action on the model
  getLabelSelector fetch this button's lable from the model
  getMenuSelector fetch a pop-up menu for this button from the model
 
  Any of the above selectors can be nil, meaning that the model does not supply behavior for the given action, and the default behavior should be used. For example, if getStateSelector is nil, then this button shows the state of a read-only boolean that is always false.
 
  The model informs its view(s) of changes by sending #changed: to itself with getStateSelector as a parameter. The view tells the model when the button is pressed by sending actionSelector.
 
  If the actionSelector takes one or more arguments, then the following are relevant:
  arguments A list of arguments to provide when the actionSelector is called.
  argumentsProvider The object that is sent the argumentSelector to obtain arguments, if dynamic
  argumentsSelector The message sent to the argumentProvider to obtain the arguments.
 
  Options:
  askBeforeChanging have model ask user before allowing a change that could lose edits
  triggerOnMouseDown do this button's action on mouse down (vs. up) transition
  shortcutCharacter a place to record an optional shortcut key
