I understand why. I know that it's not perfect. But it's the best what's achievable within the way the filter is working. But I wouldn't go that far as saying it would be "broken". I think the result is quite acceptable with regards to the method being using. The patch I had submitted doesn't change the previous behavior without the use_alpha parameter. And when using the use_alpha parameter, the results are still useful in many cases - maybe not always. But it don't see any reason to remove this just because it's not perfect. If you would have a patch to improve the results - that would be a different story and of course very welcome.
