[Feature request] Pointer emulation

[itshog]

Would it be possible to add touch pointer emulation to Niri? By that I mean the ability to simulate mouse clicks with touch/pen input in clients which don't support touch input directly (for instance yambar, see this issue)

If I'm not mistaken this is the implementation of pointer emulation in Sway. I didn't find anything in Smithay or Cosmic upstream though.

I'd be happy to help in testing this functionality.

I guess, though I'm not sure if something might be needed on smithay side too.
