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) Change-Id: Id29356ceec810ebdbed9c3c0d8415416401fe643 Reviewed-on: https://code.wireshark.org/review/19718 Petri-Dish: Anders Broman <a.broman58@gmail.com> Tested-by: Petri Dish Buildbot <buildbot-no-reply@wireshark.org> Reviewed-by: Alexis La Goutte <alexis.lagoutte@gmail.com>
