示例1:
/*
* Reconstruct the vertical margin before the line |aLine| in order to
* do an incremental reflow that begins with |aLine| without reflowing
* the line before it. |aLine| may point to the fencepost at the end of
* the line list, and it is used this way since we (for now, anyway)
* always need to recover margins at the end of a block.
*
* The reconstruction involves walking backward through the line list to
* find any collapsed margins preceding the line that would have been in
* the reflow state's |mPrevBEndMargin| when we reflowed that line in
* a full reflow (under the rule in CSS2 that all adjacent vertical
* margins of blocks collapse).
