This protocol declares an interface for classes that draw
text
attachments and handle mouse events within a text attachment.
NSCell implements all of the methods of this
protocol, less three: cellBaselineOffset,
setAttachment:, and attachment.
NSTextAttachmentCell extends
NSCell's interface by
implementing these three methods.
