Up to now, we passed a "shiftPressed" flag to the individual selection functions. To be more general replace by a struct with "shift" and "ctrl" flags. While doing this: 1) Move the struct into a new statsselection file for better encapsulation. 2) Change shift to control in the scatter series, since individual selection of items is usually done with control, not shift. Shift usually means "select range". Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
