Given that JUCE pixels are stored premultiplied, I wonder if it's a waste of resources to even try to blur the alpha channel.

What does blurring actually conceptually do to the alpha channel
Doesn't it "break" the pre-multiplied-ness to mess with alpha directly?
What precedent is there, what do other implementations do?
