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