Re: Need slightly better logic for blinking gifs

I was a little rushed this morning heading out the door, so didn't
completely dump my brain in my earlier message:

    skip> I don't think I can just blindly overwrite one frame with the next

The implication I should have stated explicitly is that we need to select an
image that's most likely the one with text in it.  If spammers are going to
blink their GIFs I suspect one or more of the images will have to be mostly
background, while other messages will have to be a mixture of colors.  That
suggests choosing one based on histograms.  Another possibility is to decide
which color is the background, make it transparent, then overlay all the
images on top of each other.

I don't have time to look at this right now.  Perhaps someone else does.
