title: Constrain width of NSTextField in Interface Builder
body: <p>I would like to use interface builder to display text in an NSTextField, which I can do.  But when the text is too long to fit normally in the space provided in the interface builder layout, I need to be able to constrain in.  I see the width constraint on the NSTextField, but it dent' behave exactly as I need.  I need to display the entire string, but to squeeze the font horizontally such that it compresses the string into the available space.  Is there a way to do this?</p>
