move playground icon to SVG

[nebulon42]

Implements part of #1165 by changing the icon for leisure=playground to SVG (as requested by @mkoniecz in #1012).

Symbol (playground-16.svg)

To me, the old icon conveys the meaning better. It's hard to see that it's people sitting on the seesaw.

Agree with @math1985 - it is in particular the missing legs in the new symbol.

Also, the classic see-saw seems to be a device on the way to extinction on nowadays super-safe playgrounds. What about a swing?

[nebulon42]

I will try to make it less abstract.
@polarbearing I think a swing might be harder to depict in a clean way when also wanting to show its function. Iconic representations are good (that's why classic telephone handsets are still on the symbols), so I think we don't have to be too modern here.

Here is a less abstract version:

also with legs:

IMO the legs just add clutter, the icon also works without legs.

[matthijsmelissen]

Looks fine to me now, even without legs.

[polarbearing]

Definitely better, more human-like and more motion. The first shot was more like tokens on a board game. Works now with or without legs.

[nebulon42]

Great, I have updated the icon (without legs).

IMO the legs just add clutter, the icon also works without legs.

As another proposition to improving the new version, have you attempted to "lower" / make smaller, the pivoting stand / point, and possibly move the figures of the children more to the side? The original icon has a smaller one, which works more "natural" to my feeling. In the new icon, due to the pivoting stand being almost the same size as the "children", the icon becomes a bit abstract, like a three legged "something"...

Here I have lowered the stand by one pixel:

Old version for comparison:

Moving the children would add even more half-pixels and increase blurriness.

[matkoniecz]

Recognisable as playground, according to my small scale hallway testing.

[mboeringa]

Here I have lowered the stand by one pixel: playground-16

Old version for comparison: playground-163-16

Moving the children would add even more half-pixels and increase blurriness.

I think I indeed like the version with the smaller pivoting stand better. But let's see if others still have comments, I think it is OK now, despite the slightly more blur with the lowered stand.

[matkoniecz]

Yes, lowered stand is better.

[pnorman]

I like the lowered stand
