* NSView.m display: fix for display bug in buttons example
	* NSCell.m endEditing: fix for display bug in buttons example
	* NSTextField.m textShouldEndEditing: The changes to these three classes
    fix a display bug visible in the buttons example when the top text field is
    selected for editing and then asked to resign when the user clicks on say
    the bottom text field.  This causes a rect encompassing both views to be
    invalidated and displayed.  Beyond being inefficient this also causes a
    display glitch given the current drawing methodology.
