Replace PNG with SVG icons

Context

• In earlier versions of Android only PNG images could be used which required to provide the same images in different resolutions.
• At some point support for SVG images was added and backported to older Android versions.

Current state

• Menu and alarm icons are still implemented as PNG files.
• See drawable, drawable-*dpi, mipmap-*dpi folders.

Target state

• Menu and alarm icons are implemented as SVG files.
• If needed new SVG icons have to be found or designed. New icons should be proposed to be discussed up-front.
• Users should not notice a difference (if the same icons are used).
• SVGs are stored in the assets folder
• SVG files are prepared so they can be tinted in the future if needed.

Hints

• Programs like Inkscape and svgo are useful.
• Add multi-density vector graphics
• Vector drawables overview
• former SVGs are partially stored in the assets folder
