UI elements sizing issues

[aeronavery]

I'm not sure whether to call this a feature request or a bug. I'm leaning towards bug.

The scene editor is not properly WYSIWYG (what you see is what you get). The sizes displayed in the Scene Editor are different than what is displayed during Test Mode and on AppGameKit Player.

Here are two screenshots of what's displayed in the scene editor versus what is displayed in Test Mode.

Scene Editor:

Test Mode:

As you can see the font size of the Text label is smaller, and the font size of the Button's text is larger. The font sizes in the auto-generated Script are correct so I'm not sure what's going wrong here.
