allow custom scaling of attachment thumbnail

[adrian-herscu]

For performance reasons, I am transforming my screenshots to use less colors and also scale them down to 1/4 so their sizes are now approx. 300x550 and weight less than 14KB.

Now I am discovering that the attachment thumbnails are no longer visible :(
This is due to hardcoded scaling value, currently set at 0.02.

What would be a good solution? I think a fix thumbnail size would make more sense, right?

I would say that this would be the cheapest solution :)

Sounds reasonable as long as it will display proportionally on different screen resolutions.

I just looked into the code and it is already implemented that the thumbnail should have a minimal width and height of 20px. Maybe this is just too small?

Ok, after understanding the code, I think the minimal size is not applied correctly...

Fix is released with v0.18.0. Can you verify that it works for you?
