// 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.

  BOOL fastResizeMode_;
}

// Turns fast resizing mode on or off, which determines how this view resizes
// its subviews.  Turning fast resizing mode off has the effect of immediately
// resizing subviews to fit; callers do not need to explictly call |setFrame:|
// to trigger a resize.
