- * Repacking is seperate from resizing since a box's size depends on

- * contentwidths of siblings both before and after the box, which in
- * turn depend on all descendents of the siblings. FIXME

+ * reflow. Repacking assigns boxes to the appropriate grid
+ * coordinates within the parents and computes
+ * contentwidth/contentheight. Resize computes actual size and
+ * position.

* A note on coordinates: the Box class represents regions
* internally as x,y,w,h tuples, even though the DoubleBuffer class
