Only Segments that are completly within the rectangle will be selected.

points is a list of Point objects. The first and last points in the list are diagonally opposite corners of the rectangle. Any other points in the list will be ignored.

The shift and ctrl parameters govern how the current selection (i.e, the set of Segments defined by this operation) is merged with the previous selection (the Segments already selected) to form a new selection, as shown in Table 6.1. They indicate whether (True) or not (False) the shift and control keys were depressed during the mouse click that initiated this command.
