// To do:
// - Resize or show + hide the Time and Comment axes, possibly via one of
//   the following:
//   - Split the time, diagram, and comment sections into three separate
//     widgets inside a QSplitter. This would resemble the GTK+ UI, but we'd
//     have to coordinate between the three and we'd lose time and comment
//     values in PDF and PNG exports.
//   - Add separate controls for the width and/or visibility of the Time and
//     Comment columns.
//   - Fake a splitter widget by catching mouse events in the plot area.
//     Drawing a QCPItemLine or QCPItemPixmap over each Y axis might make
//     this easier.
// - For general flows, let the user show columns other than COL_INFO.
// - Add UTF8 to text dump
// - Save to XMI? http://www.umlgraph.org/
// - Time: abs vs delta
// - Hide nodes
// - Clickable time + comments?
// - Incorporate packet comments?
// - Change line_style to seq_type (i.e. draw ACKs dashed)
// - Create WSGraph subclasses with common behavior.
// - Help button and text
