Changes

The layout changes -- see also the "XUL' and XBL2" section of this roadmap -- center around David Baron's "reflow branch", the aim of which is to eliminate reflow commands and types, and significantly reduce the complexity of the Gecko layout model. This is the first change to global layout architecture in several years, and it is hoped that it will address many problems related to incremental reflow. In addition, it should simplify some problems that are not practically soluble with the current architecture, such as support for inline-table.
