-// FEATURE: fastpath for rows=1/cols=1
-// FEATURE: mark to reflow starting with a certain child
-// FEATURE: separate mark_for_reflow and mark_for_resize
-// FEATURE: make all methods final
-// FEATURE: use a linked list for the "frontier" when packing
-// FEATURE: or else have a way to mark a column "same as last one"?
-// FEATURE: reintroduce surface.abort

-/**
- * <p>
- * Encapsulates the data for a single XWT 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.
