Detailed Description

Class holding information about wrapping a text_buffer_t.

This class is required by edit_window_t and text_buffer_t to present the user with a wrapped text. Except for in the function find_line, it uses the text_coordinate_t class in a special way: the pos field is used to store the index in the array of wrap points for the line indicated by the line field.
