Module buffer 

The primary Widget of Duat, used to display buffers.

Most extensible features of Duat have the primary purpose of serving the Buffer, such as multiple Cursors, a History system, RawArea::PrintInfo, etc.

The Buffer also provides a list of printed lines through the Handle::printed_lines method. This method is notably used by the LineNumbers widget, that shows the numbers of the currently printed lines.
