/** Multi-line attributed text that can be displayed by one or more Gtk::TextView widgets.
 *
 * Text in a buffer can be marked with tags. A @link Gtk::TextTag Gtk::TextBuffer::Tag@endlink is an attribute that can be applied to some range of text. For example, a tag
 * might be called "bold" and make the text inside the tag bold. However, the tag concept is more general than that; tags don't
 * have to affect appearance. They can instead affect the behavior of mouse and key presses, "lock" a range of text so the user
 * can't edit it, or countless other things. A tag is represented by a @link Gtk::TextTag Gtk::TextBuffer::Tag@endlink object.
 * One @link Gtk::TextTag Gtk::TextBuffer::Tag@endlink can be applied to any number of text ranges in any number of @link Gtk::TextBuffer Gtk::TextBuffers@endlink.
 *
 * Each tag is stored in a @link Gtk::TextTagTable Gtk::TextBuffer::TagTable@endlink. A tag table defines a set of tags that can be used together. Each buffer has one tag
 * table associated with it; only tags from that tag table can be used with the buffer. A single tag table can be shared between
 * multiple buffers, however.
 *
 * Most text manipulation is accomplished with iterators, represented by an @link Gtk::TextIter iterator@endlink. The iterator can
 * be used to navigate over characters, words, lines, and sentences.
 *
 * But iterators can't be used to preserve positions across buffer modifications. To preserve a position, the
 * @link Gtk::TextMark Gtk::TextBuffer::Mark@endlink object is ideal. There are two marks built-in to GtkTextBuffer; these are
 * named "insert" and "selection_bound" and refer to the insertion point and the boundary of the selection which is not the
 * insertion point. If no text is selected, these two marks will be in the same position. You can manipulate what is selected and
 * where the cursor appears by moving these marks around.
 *
 * Text buffers always contain at least one line, but may be empty (that is, buffers can contain zero characters). The last line
 * in the text buffer never ends in a line separator (such as newline); the other lines in the buffer always end in a line
 * separator. Line separators count as characters when computing character counts and character offsets. Note that some Unicode
 * line separators are represented with multiple bytes in UTF-8, and the two-character sequence "\r\n" is also considered a line
 * separator.
