/**
* 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.
