   7  * This extension adds bookmark support. The method to add a bookmark is:
   8  *
   9  * function Bookmark(string txt [, int level [, float y]])
  10  *
  11  * txt: the bookmark title.
  12  * level: the bookmark level (0 is top level, 1 is just below, and so on).
  13  * y: the y position of the bookmark destination in the current page. -1 means the current position. Default value: 0.
  14  *
  15  * The title must be encoded in ISO Latin-1.
