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.
