+/**
+ * <p>
+ * Encapsulates the data for a single Ibex box as well as all layout
+ * rendering logic.
+ * </p>
+ *
+ * <p>The rendering process consists of four phases; each requires
+ * one DFS pass over the tree</p>
+ * <ol><li> <b>repacking</b>: children of a box are packed into columns
+ * and rows according to their colspan/rowspan attributes and
+ * ordering.
+ * <ol><li> <b>reconstraining</b>: Minimum and maximum sizes of columns are computed.
+ * <li> <b>resizing</b>: width/height and x/y positions of children
+ * are assigned, and PosChange/SizeChanges are triggered.
+ * <li> <b>repainting</b>: children draw their content onto the PixelBuffer.
+ * </ol>
+ *
+ * The first three passes together are called the <i>reflow</i> phase.
+ * Reflowing is done in a seperate pass since PosChanges and
+ * SizeChanges trigger an Surface.abort; if rendering were done in the same
+ * pass, rendering work done prior to the Surface.abort would be wasted.
