- * The class LayoutManager implements a vertically split layout that takes up
- * the whole window, and provides a draggable bar to resize the left and right
- * panes. Its elements are layed out as follows:
- *
- *
- *                  <<-- sizer -->>

- *  +----------------------++----------------+
- *  |      topbar          ||                |

- *  +----------------------++----------------+
- *
- * The "topbar" and "bottombar" have a fixed height which is determined
- * by their initial content height. The rest of the boxes fill to occupy the
- * remaining space.
- *
- * The consumer provides DIVs for each of these regions, and the LayoutManager
- * positions them correctly in the window.
