Function
Different
to Shake's version, the preset of CGM's plug-in just blurs
the alpha channel of the image. By default a gaussian blur
is used, but you can change the filter for both X and Y.
It's very important to keep an eye on the spread function.
Because the workspace is infinite, you can select which
pixels will be used for the blur calculation - only the
pixels inside the image, or outside as well. If you are
getting clipping or dark edges on your final image you should
toggle Blur Alphas's spread parameters.
