Implements part of #1165 and moves tourism=museum to SVG.
Icon can be found here: https://github.com/nebulon42/osmic/blob/master/tourism/museum-16.svg

you shouldn't specify a fill since it's coming from marker-fill in the MSS. None of the other style attributes are necessary either

[nebulon42]

This comes from Inkscape, unfortunately (except the fill). I don't think it is feasible to edit all the sources and I didn't notice problems with the fill. For me these are subtleties, but I can change it if you think it is better.

[pnorman]

what do you think of this?

<?xml version="1.0" encoding="UTF-8"?>
<svg xmlns="http://www.w3.org/2000/svg" width="100%" height="100%" viewBox="0 0 16 16">
<path d="M 8,1 2,3 2,4 14,4 14,3 Z
M 1,14 2,12 14,12 15,14 Z
M 2,5 2,6 3,6 3,12 13,12 13,6 14,6 14,5 Z
M 5,12 l 0,-5 a 1,1 0 0,1 2,0 l 0,5 Z
M 9,12 l 0,-5 a 1,1 0 0,1 2,0 l 0,5 Z"/>
</svg>

(pixel grid added)
I think it balances the weight of the top and bottom better

[nebulon42]

Definitely an improvement. Maybe we should also make it less tall then?

The spiky areas between the columns where intended to look more crisp, but I'm not sure if that is necessary.

That might be a good idea.

At 1x resolution the difference is between them being 50% gray pixels and 25% gray pixels, no sharpness difference.

I think the curves will look better for 2x and print. For 2x the line is

1.0 0.5 0.5 1.0
0.5 0.0 0.0 0.5

and the curve is

1.0 0.2 0.2 1.0
0.2 0.0 0.0 0.2

Good argument, I have updated the icon.

Looks nice!

Agree, simple but effective.
