Add a != operator to ViewportArguments

[Jacky Jiang]

As suggested on bug 87438, we should add a != operator to ViewportArguments.
Hopefully this is right thing to do. Open for discussions in case there are different ideas.

[Kenneth Rohde Christiansen]

You should explain better why that it needed. I actually believe that we used to have that.

[Antonio Gomes]

I think it is only about convenience.

in blackberry/ we have 3 or 4 cases of

if (!(m_viewportArgument == DefaultViewportArguments)) {
...
}

Any update here? Looks straightforward and useful...

You don't want this duplicated code.  What you should do is this:
return !(this == other);

Thanks, should be this !(*this == other) if we don't want duplicate this code I think.
