Add Dask

[mrocklin]

This adds Dask to the Python 3 statement.

One question: I noticed that all of the images here are PNG. I uploaded an SVG (this just happens to be the most convenient for me at the moment) but I'd be happy to convert it as well.

I've asked for a few other Dask maintainers to +1 this PR to build authority behind it.

+1 from me, thanks for adding this @mrocklin!

SVG v. PNG: whichever is smallest! See #200. So probably SVG. :)

[mrocklin]

I'm definitely in favor of SVG generally. When I ran Jekyll locally I did find that the logo was quite small, so there might need to be a small CSS change somewhere.

There's an automatically generated preview as well: https://deploy-preview-239--python3statement.netlify.com/

Inspecting the icon, it looks like we set max-width and max-height CSS properties, but the size the SVG 'wants' to be is smaller than that. I guess that's something that can be set in the SVG file itself? I don't think we should set height and width for all logos, because that stretches them to fill the bounding box.

We can sett a min-width: 100px on the wrapping <li>, that seem to do the trick; and affect mostly the dask logo.

[Carreau]

Let's get that in; we can refine.

Thanks.

Putting dask.svg through https://svgtopng.com:

 24K dask.png
2.3K dask.svg

After squashing:

  12K dask.png
 2.3K dask.svg

Big win for SVG.

Now we just need pngtosvg.com! :-P

Well svgs can include rasterized data right ?
Otherwise it's pretty easy to make lots of colored squares in SVG :-)
