+// The whole selection thingie in this class is somewhat... suspicious to me.
+// some oddities:
+// * method parameters named like members (and used in both semantics within the method!)
+// * the multi selection flag is sometimes used as if it is for row selection, sometimes as if
+//   it's for column selection, too (and sometimes in an even stranger way :)
+// * it is not really defined like all these hundreds selection related flags/methods work together
+//   and influence each other. I do not understand it very well, but this may be my fault :)
+// * There is a GetColumnSelection, but it can't be used to determine the selected columns (at least
+//   not without a const_cast)
+//
+// We should clearly define this somewhere in the future. Or, even better, we should re-implement this
+// whole class, which is planned for a long time :)
+//
