-//FIXME: chatline doku
-//!\brief Containing the layout and providing the rendering of a single message.
-/** A ChatLineOld takes a Message object,
- * formats it (by turning the various message types into a human-readable form and afterwards pumping it through
- * our Style engine), and stores it as a number of QTextLayouts representing the three fields of a chat line
- * (timestamp, sender and text). These layouts already include any rendering information such as font,
- * color, or selected characters. By calling layout(), they can be quickly layouted to fit a given set of field widths.
- * Afterwards, they can quickly be painted whenever necessary.
- *
- * By separating the complex and slow task of interpreting and formatting Message objects (which happens exactly once
- * per message) from the actual layouting and painting, we gain a lot of speed compared to the standard Qt rendering
- * functions.
