inline Size<T>& Expand(T w, T h); inline Size<T>& Expand(const Size<T> & sz); inline Size<T>& Expand(T value);
Expand expands a size by adding a fixed value to each of its components. The following expression may be used to represent the result:
(Width, Height) = (Width + [sz.Width, value, w], Height + [sz.Height, value, h])
A Size reference to the current string whose components are determined by adding alternate values to its original components.
