[Image-SIG] Radius bug with GaussianBlur

[Tiberio Uricchio]

Hi,
i just wanted to report a simple bug in ImageFilter.GaussianBlur:

class GaussianBlur(Filter):
    name = "GaussianBlur"

    def __init__(self, radius=2):
        self.radius = 2

    def filter(self, image):
        return image.gaussian_blur(self.radius)

As you can see, radius is always fixed at value 2 instead of using the
argument value.
