/** 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.
