Berthold Stoeger d63d4cd3c3 statistics: implement rectangle selection in scatter plot
Allow the user to select regions of the scatter plot using
a rectangular selection. When shift is pressed, do an
incremental selection.

Unfortunately, the list-selection code is so slow that this
becomes unusable for a large number of selected dives.
