I've thought I'd be able to do this by weekend, but things became too complicated and time consuming. I mean, I had time for this a year ago, but not now. TBH my system already has those icons and some others, and it works fine for me, so I really don't want to mess with those SVG-optimizers, dynamic colors, that involve patching files after every edit, etc. I'll appreciate if someone finish this, but I've realized that I have neither time nor will, to do this.

Phabricator unfortunately doesn't offer SVG previews, so posting new screenshots every time you update the diff is appreciated. :)

• made controll buttons 1.2px instead of 1px. Now 16 and 22 px icons will have slope somewhat between proposed variants. Looks crisp enough on my setup

fix links

Changed icons so they look crisp

Understood. Yeh, now I see it. I have very poor eyesight, I'll fixt it

@andreyorst, if you're still around, we can review this patch and land it once necessary changes are made.
