Add Goodput graph:
- measures rate of ACKed bytes (including SACKed bytes)
- useful to compare to throughput during slow-start to estimate
bottleneck rate
Add graph selection checkboxes to multi-plot graphs:
- most important for Throughput, since there are good cases
for showing a subset of graphs at once
- also added for Window Scale, since the addition is similar
to that for Throughput
Minor bug fixes:
- allow zoom rect to work when growing in any direction
(not just right and up)
- keep stray mouse clicks from re-doing a previous zoom
- hide rubber band if active when keypress changes mouse mode
to drag
- allow mouse clicks on open space or grpah to return to default focus
(i.e. focus on graph)

Modifications to RTT graph:
- change x-axis to time (s) rather than sequence number
[ avoids sequence number wraparound ambiguity, plus
easier to correlate RTT changes to tcptrace graph ]
- change RTT computation to properly handle acks to GSO packets
- change RTT computation to take SACK blocks into account
Bug fixes:
- eliminate potential memory leak if some packets are unacked
- ensure RTT graph is shown if TCPGraph window is opened to it directly

This metric is commonly used as an estimate of the sender's congestion window.
[ when examining a capture taken from the sender ]

Add get_tcp_stream_count() to the TCP dissector and modify
graph_segment_list_get() to allow matching based solely on a stream.
Use text instead of icons for the mouse click behavior buttons. Remove
their PNG resources since we aren't using them any more. Fix setting the
cursor in the graph widget.

Rename some methods. Add the ability to toggle time and sequence number
origins. Add more keyboard shortcuts. Comment out abs_secs abs_usecs in
the segment struct since it looks like we aren't using them. Make sure
we stay in the same TCP stream.

Show the time values in ms instead of s. Add a button and keyboard
shortcut to switch the connection direction. Move more code to
tap-tcp-stream.c. Update our axis labels.

GTK+: Fix what appears to be an off-by-one error in the MA period (21
segments instead of 20). Throw away our initial segment length instead
of subtracting it from the moving sum, which skews the sum.
Qt: Add the througput graph. Use bits/s for the throughput y axis. Let
the user switch between graph types. The dialog hangs when doing this. I
haven't been able to track down the cause. Remove some unused code.
Both: Tell the user that we're using a 20 segment moving average. Move
more routines to tap-tcp-stream.[ch].

QCustomPlot data sets are made up of keys (x axis by default) and values
(y axis). It looks like we can have multiple values for a given key
(i.e. we can show multiple sequence numbers for a given timestamp) but
QCPItemTracers can only be positioned by a key and not a key+value pair.
This makes our graph selection behavior a bit different compared to the
GTK+ version. We can only select one segment for a give timestamp but
our selection targets are much larger (the height of the graph).
Add a map for segment data so we don't have to iterate to find them. Use
UTF8_RIGHTWARDS_ARROW where appropriate. Set a window title. Tell the
user what will happen if he or she clicks. Disable graph selection.

Add the QCustomPlot widget. Thanks to Emanuel Eichhammer for granting a
license change. Move some common code from ui/gtk/tcp_graph.c to
ui/tap-tcp-stream.[ch]. Get rid of tcp_graph_selected_packet_enabled().
It was only used in the menu code and didn't match what we were doing
elsewhere.
Still quite a bit of work to do but it's a promising start.
