/**
 * The class overrides default method for computing size in Composite by
 * accepting size returned from layout managers as-is. The default code accepts
 * width or height hint assuming it is correct. However, it is possible that
 * the computation using the provided width hint results in a real size that is
 * larger. This can result in wrapped text widgets being clipped, asking to
 * render in bounds narrower than the longest word.
