"""Builds the Material icon pack the client ships (core/src/main/resources/gfx/material).

The pack is in TeamSpeak's own format (settings.ini + SVGs), so both frontends draw it
through the same code as any TeamSpeak pack. The art is Google's Material Icons
(Apache 2.0), the set the Android frontend was designed with.

Monochrome icons are filled with `currentColor`, which the frontends replace with the
interface's text colour; status icons carry the fixed colours TeamSpeak gives them.
