Move the viewport up.

@param isUnit indicates if the move is a unit move. If {@code true}, this argument has precedence to the other arguments.
@param isLarge indicates if the move is a large move. If {@code true}, this argument has precedence
to the very large argument.
@param isVeryLarge indicates if the move is a very large move.
