Desenha um sector circular (fatia) delimitado por um retângulo definido por <em>x</em>,<em>y</em>,<em>largura</em>,<em>altura</em>. O vertice do sector será no centro to rectângulo. Os ângulos serão contados a partir da posição de (12Horas = 0 radianos) e serão medidos na direcção dos ponteiros do relógio e em radianos.
