Tilføjet:
- Rektangel bliver tegnet, når man dragger musen for at zoome ind.
- Anti-aliasing på linjerne, når man zoomer tilpas meget ind (linjerne bliver smoother og ikke lige så jagged).

Til Sjurdur: Jeg fik ikke helt implementeret dine ændringer. Forhåbentlig kommer det her push ikke til at overwrite dine ændringer. Hvis det ikke gør, så er det kun i mouseDragged metoden i Controller klassen at den største ændring ligger i. Anti-aliasing ligger i paint metoden, og en anden ændring er, at jeg har delegeret tegneopgaven til en metode drawRect i stedet for at gøre det i paintmetoden, og renamed den tidligere drawRect metode til assignRect.
New modified version. Implemented Sjurdur's stuff.
The drawn rectangle when dragging the mouse for zoom is now painting much faster.
