The Breeze theme's icon set (#45).

breeze-icons 6.31.0, Uri Herrera and the KDE Visual Design Group.
https://invent.kde.org/frameworks/breeze-icons, commit 60ca51729f00b85813f01580fc9e85723245054d.
Licence: GNU LGPL v3 or later, with KDE's clarification for artwork (LICENSE, beside this file;
the GNU GPL v3 it builds on is Zephyrus's own LICENSE, at the top of the repository).

Each file is one of the theme's icons, unchanged, renamed to the need Zephyrus uses it for
(crates/app/src/themeicons.rs lists them):
- 16/: icons/<context>/16/<icon>.svg, drawn for 16 pixels.
- 24/: icons/<context>/22/ or 32/<icon>.svg, drawn at 24 pixels and up.
- <need>-symbolic.svg: a one-colour icon (KDE's ColorScheme-Text); Zephyrus draws its greys in the
  theme's text colour as it reads it, as KDE does, and keeps its highlight and warning colours.
- <need>.svg: a colour icon, drawn as it is.

Which icon each need is (and the stand-ins, where Breeze has no icon of that meaning):

Zephyrus's own, drawn for Zephyrus in Breeze's flat style (GPL-3.0-or-later, as Zephyrus), at 16, 24, 32 and
48 pixels: ft-pdf (a page with "PDF" letters, ft-pdf.png), instead of Breeze's application-pdf,
whose mark recalls a brand's, and ui-to-tray (a window going down to the notification area,
where Breeze has no icon of that meaning), a one-colour picture (ui-to-tray-symbolic.png) drawn
in the theme's text colour. Either can be swapped for another file of the same name.
