 * - Graphs
 * - Get AIX to work
 * - Check for end of packet in dissect_* routines.
 * - Playback window
 * - Multiple window support
 * - Add cut/copy/paste
 * - Handle snoop files
 * - Fix progress/status bar glitches?  (GTK+ bug?)
 * - Create header parsing routines
 * - Check fopens, freads, fwrites
 * - Make byte view scrollbars automatic?
 * - Make byte view selections more fancy?
