Transformación 2D | Rotación de objetos

Tenemos que rotar un objeto en un ángulo dado sobre un punto de pivote dado e imprimir las nuevas coordenadas.
Ejemplos: 

Input : {(100, 100), (150, 200), (200, 200), 
         (200, 150)} is to be rotated about 
          (0, 0) by 90 degrees
Output : (-100, 100), (-200, 150), (-200, 200), (-150, 200)
