blur-effect: fix paint volume padding

Browse Source 
For the blur effect we use a BLUR_PADDING constant to pad out the volume
of the source actor on the x and y axis. Previously we were offsetting
the origin negatively using BLUR_PADDING and then adding BLUR_PADDING
to the width and height, but we should have been adding 2*BLUR_PADDING
instead.
