- when presented on dark background, the jaggies are too prominent

Fixes #226

- fine tune 16x16s
- add mimetypes
- link inode-directory, hopefully addressing folder.png

- we no longer render fullcolor into bitmaps

Invalidates #211

Fixes #224

  Improve legibility of the outlines at 32x32. nudge emblems
  for pixel grid at 32x32 too

* Hoping to cover all the broken model/* mimetypes with this generic
  fallback

(hopefully) fixes #225

See #221

adresses #221

Fixes #223

- based on design review during this week's call, lower the depth of
  of the folder. gets a bit fuzzy at 32, but not terrible.

- similarly to the Boxes app, white shapes are hard
  to present on white-ish backgrounds
- shifting the problem from white bg towards light grey
- gradients on large surfaces are generally off-style, but work
  in our favor in this case. worth breaking the rule

Improves gnome-control-center#2284

- round all the VPN icons and sync up the wire with the
  other networked objects

Fixes #213

- rounded and consistent with networked device style

- use the new rounded style
- sync with assets in devkit
- clearer metaphor for workgroup

- some assets weren't exported

- scalables get installed now! Big thanks to @btwilliam on matrix

- maybe scalables need to be in front of symbolic to take precedence?

See the struggle at #215

Only god knows how the icon theme lookup works these days. Perhaps separating fullcolor out
of the symbolics will prevent the recoloring.

See nautilus#2587

Sadly gtk3 apps like Boxes, that aren't going to be ported any time soon, still depend on the hack.

This reverts commit e148bf86.

- this no longer works and misbehaving apps still get a huge spinner

- removed mimetype and places lowres 22,24,32,48. Will need to recreate
  some of the fuzzier ones. Would be nice if we could live without 48x48
  16x16 could be hand crafted in a pixel editor

- AFAIK saved searches don't exist in Nautilus. Keep lowres only.

- Nautilus no longer uses the drag accept and open states. symlink the folder
  just so that 3rd party apps don't break in the world of theming.

- text preview doesn't exist for years, but who knows where this
  creeps up on us.

- rogotten export and source
