sfText_getGlobalBounds && remove reference from time comparison

Sorry for not starting a pull request, I was caught up in some stuff and didn't bother figuring out how to do one.
If I find some more stuff "missing", I will write more commits.

Adds getGlobalBounds to text for text size comparisons or setting the origin to the middle of the text.
I also removed ref from Time comparisons so I didn't have to make a new Time to just do simple time comparisons.
What it was before to me:

Time Second = Time.seconds(1);
Clock Clock = new Clock();
if(Clock.getElapsedTime().OpCmp(Second) == 1)
         //Dosomething

What it is now, doing the same thing:

Clock Clock = new Clock();
if(Clock.getElapsedTime() >= Time.seconds(1))
        //DoSomething

I'm still not %100 comfortable with GitHub but I thinks its cool, so help me out if I do something wrong.
