The app icon in Ubuntu Bionic Dock and GNOME Activities Favorites (e.g., Fedora 29) looks ugly due to improper scaling (screenshots).

There are some possible solutions:
1. Qt::SmoothTransformation does not work as expected (#14990)
2. Multiple QPixmaps added by QIcon::addPixmap() do not work in this case (https://github.com/bitcoin/bitcoin/pull/14990#issuecomment-448127312; Qt bug?)
3. Use SVG images as icons directly
An icon engine that supports SVG is included with Qt since version 4.2 (tested: it works).
