Flatpak / Flathub

[eszlari]

It would be nice, if glmark2 could be made available as a Flatpak on Flathub:

Getting glmark2 to compile and run in a Flatpak is easy enough, I wrote a manifest for it here: https://github.com/X-m7/flathub/tree/glmark2

The issue with submitting to Flathub though is that they want things like AppStream metadata, screenshots, and icons, which glmark2 doesn't officially have. The first two I can try to make myself, but I don't know what kind of icon would work here.
