It's simply not true that 1-2 pixel blur increments are not noticeable. It
depends what you're doing. Sometimes the subtlety is what matters. As I
say, I'm doing perhaps 750x450 website graphics, but some people may be
doing 2048x1536 wallpapers.

I've just tried a logarithmic scale and it's useless. But I also tried a
polynomial scale with reasonably good results. I've attached an SVG.

The second of those workarounds had already occurred to me, but I don't
think either of them are that easy for users, even compared to copy and
pasting the percentage value from the spinner - which clearly won't work,
but which is the most trouble I would really consider going to to get it
right.

I don't suppose the slider could be relative to object size, while the
spinner shows absolute standard deviation, could it?
