-// FIXME: are traps on x/y meaningful?
-// FIXME: if we trap on cols, then set rows to 0 (forcing cols to 1), does the cols trap get triggered?
-// FIXME: if we change min{width/height}, thereby forcing a change to max{min/height}, does a trap on those get triggered?
-// FIXME: trap on numchildren? replaces ChildChanged?
-// FIXME: trap on visible, trigger when parent visibility changes
-
-// FIXME: ax/ay nonsense
-// FIXME: mouse move/release still needs to propagate to boxen in which the mouse was pressed and is still held down
-
-// FEATURE: mark to reflow starting with a certain child

-/**
- * <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>pack()</b>: each box sets its childrens' row/col
- * <ol><li> <b>constrain()</b>: contentwidth is computed
- * <li> <b>resize()</b>: width/height and x/y positions are set
- * <li> <b>render()</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 SizeChanges
- * trigger a Surface.abort; if rendering were done in the same pass,
- * rendering work done prior to the Surface.abort would be wasted.
