* 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
