Not sure, 

CSS has the overflow property (visible | hidden | scroll) that specifies what would happen in this case.

Do we have this concept in JFX ?

What happen if I place a Rect(10, 10, 100, 100) in a Region that is (50, 50) ? it overflows right ?

We could move CSS support up to Parent, or make sense of DIV having a specific width and height (width is useful because we then wouldn't need "wrappingWidth" -- ie, they are the same thing, and it would be resizable so adding it to a layout container would perfect. But what to do about the height? If the height isn't right, do we just flow the text beyond the given height? Kind of a weird case). Or we can add CSS Background / Border support to TextFlow independent of the Region.
