    // other case we can use analogue arguments).
    // All cols k with m<k<=n have been shifted left on pos, the former col m now has pos n.
    // In the model this affects a range of cols x to y, where x<=m and y<=n. And the number of hidden cols
    // within this range is constant, so we may calculate the view pos from the model pos in the above way.
    //
    // for instance, let's look at a grid with six columns where the third one is hidden. this will
    // initially look like this :
    //
    //				+---+---+---+---+---+---+
    // model pos	| 0 | 1 |*2*| 3 | 4 | 5 |
    //				+---+---+---+---+---+---+
    // ID			| 1 | 2 | 3 | 4 | 5 | 6 |
    //				+---+---+---+---+---+---+
    // view pos 	| 0 | 1 | - | 2 | 3 | 4 |
    //				+---+---+---+---+---+---+
    //
    // if we move the column at (view) pos 1 to (view) pos 3 we have :
    //
    //				+---+---+---+---+---+---+
    // model pos	| 0 | 3 |*2*| 4 | 1 | 5 |	// not reflecting the changes, yet
    //				+---+---+---+---+---+---+
    // ID			| 1 | 4 | 3 | 5 | 2 | 6 |	// already reflecting the changes
    //				+---+---+---+---+---+---+
    // view pos 	| 0 | 1 | - | 2 | 3 | 4 |
    //				+---+---+---+---+---+---+
    //
    // or, sorted by the out-of-date model positions :
    //
    //				+---+---+---+---+---+---+
    // model pos	| 0 | 1 |*2*| 3 | 4 | 5 |
    //				+---+---+---+---+---+---+
    // ID			| 1 | 2 | 3 | 4 | 5 | 6 |
    //				+---+---+---+---+---+---+
    // view pos 	| 0 | 3 | - | 1 | 2 | 4 |
    //				+---+---+---+---+---+---+
    //
    // We know the new view pos (3) of the moved column because our base class tells us. So we look at our
    // model for the 4th (the pos is zero-based) visible column, it is at (model) position 4. And this is
    // exactly the pos where we have to re-insert our column's model, so it looks ike this :
    //
    //				+---+---+---+---+---+---+
    // model pos	| 0 |*1*| 2 | 3 | 4 | 5 |
    //				+---+---+---+---+---+---+
    // ID			| 1 | 3 | 4 | 5 | 2 | 6 |
    //				+---+---+---+---+---+---+
    // view pos 	| 0 | - | 1 | 2 | 3 | 4 |
    //				+---+---+---+---+---+---+
    //
    // Now, all is consistent again.

    // the user expected the latter but there really is no good argument against our method ;) ...)
