// TODO
// 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 :)
//
