 // A Cocoa view that supports an alternate resizing mode, normally used when
 // animations are in progress.  In normal resizing mode, subviews are sized to
 // completely fill this view's bounds.  In fast resizing mode, the subviews'
 // size is not changed and the subview is clipped to fit, if necessary.  Fast
 // resize mode is useful when animating a view that normally takes a significant
 // amount of time to relayout and redraw when its size is changed.
