Thanks.  I can create the alpha mask.  I understand how to do that.  The 
problem I'm having is that I have an image with some alpha in it and now 
I want to apply the mask to the image.  The idea is to get an image that 
is circular, where everything outside the circle is blank, and where the 
edges of the image are anti-aliased so when it is placed on top of a 
background, it looks like a neat circle without jagged edges. 

I'd like to be able to do this without going through the image pixel by 
pixel, but that might be the best way to accomplish it, I guess.
