Parameters:
ShadeReason - If this is non-NULL, and if the returned OpState [OUTPUTS] indicates that this Op is shaded, it will be returned filled in with a string describing why the Op is shaded. Otherwise this string is left untouched
OpDesc - The descriptor with which we'll be invoked

Returns:
An OpState indicating this Op's state
