+ * select parts, right-click, "display in new score window" or "display per-track in new score window"
+ * or "display in existing window -> 1,2,3,4" or "display per-track in existing..."
+ *
+ * ScoreCanvas has a list of note systems, consisting of the following:
+ * * all parts included in that view
+ * * eventlist, itemlist
+ * * used clef, transposing/octave settings
+ * * enum { NOT_GROUPED, I_AM_TOP, I_AM_BOTTOM } group_state
+ * NOT_GROUPED means "single note system"
+ * I_AM_TOP and I_AM_BOTTOM mean that the two systems belong
+ * together
+ *
+ * when redrawing, we iterate through all systems.
+ * we add a distance according to group_state
+ * then we draw the system. if group_state is I_AM_BOTTOM, we
+ * draw our beams longer/higher, and we draw a bracket
+ *
+ * when clicking around, we first determine which system has been clicked in
+ * (the systems have enough space in between, so there won't be notes
+ * from sys1 in sys2. if there are, they're ignored for simplicity)
+ * then we proceed as usual (adding, removing, changing notes)
