* should get widths calculated the same way as top and bottom, but they will be rotated so the
* calculated width is stored as the rect height.
* 2. Decide if we can fit all the tabs.
* 3. When we cannot fit all the tabs we create a tab popup, and then layout the new tabs until
* we can't fit them anymore. Laying them out is a matter of adding them into the visible list
* and shifting them horizontally to the correct location.
