- * <p>
- * This is the real meat of XWT. Part of its monolithic design is for
- * performance reasons: deep inheritance heirarchies are slow, and
- * neither javago nor GCJ can inline across class boundaries.
- * </p>
- *
- * <p>The rendering process consists of three phases; each requires
+ * <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. Minimum and maximum sizes of columns are computed.
- *
+ * 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. If a PosChange or SizeChange is triggered,
- * <tt>Surface.abort</tt> will be set and the resizing process will
- * Surface.abort.
- *
- * <li> <b>repainting</b>: children draw their content onto the
- * buffer.
+ * are assigned, and PosChange/SizeChanges are triggered.
+ * <li> <b>repainting</b>: children draw their content onto the PixelBuffer.
* </ol>
*
- * The first two passes together are called the <i>reflow</i> phase.
- *
+ * 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.
- *
- * The two passes are repack and resize. Together they are known as
- * 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 PixelBuffer class
- * uses x1,y1,x2,y2 tuples.
