Thanks!
Only if you have a vector image.
And for which sizes should I downscale the PNG? Should I do it at all?
3. In the `debian` folder created by dh_make I noticed a file called `menu.ex`. What's the purpose of debian/menu?The Debian menu system, used by some old or obscure window managers not supporting the XDG one. https://www.debian.org/doc/packaging-manuals/menu.html/
So I should provide an entry for both /usr/share/menu and /usr/share/applications, shouldn't I?
