Container Clipping Not Represented

[Matt Hicks]

Here's my prototype implementation:

When you click on one of the two rectangles it selects it and uses fracs().rects.viewport to determine how to position the outline. As you can see, when the rectangle is clipped by the scrollbar it doesn't properly represent that in fracs.

I'm dumping fracs information to the JavaScript console upon update.
