Implement single-pixel-buffer-v1?

[flexibeast]

Recent versions of the shotman screenshot GUI don't work under Wayfire, due to Wayfire not implementing the single-pixel-buffer-v1 interface. The shotman author linked to how this interface was implemented in Sway.

Might Wayfire also implement this interface?

Wayfire can implement this, but keep in mind that our implementation will be more complex because we do not use the default wlroots renderer. A Wayfire impl would require extending the texture type and writing the appropriate shaders.

Actually, I looked at the wlroots implementation, this should actually be very easy to add (unlike I thought initially), just the same as Sway (a few lines to set up the protocol). PRs welcome :)
