/**
*
* Encapsulates the data for a single XWT box as well as all layout
* rendering logic.
*
*
*
* 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.
*
*
* The rendering process consists of three phases; each requires
* one DFS pass over the tree
*
* - repacking: 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.
*
*
- resizing: width/height and x/y positions of children
* are assigned. If a PosChange or SizeChange is triggered,
* Surface.abort will be set and the resizing process will
* Surface.abort.
*
*
- repainting: children draw their content onto the
* buffer.
*
*
* The first two passes together are called the reflow 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 DoubleBuffer class
* uses x1,y1,x2,y2 tuples.
