visible-frame-list (and PGTK)

[Björn Bidar]

Hello,

Does `(visible-frame-list)` take the current virtual desktop into
account? If so does this also work when Emacs is build with PGTK?

For X11 Emacs can use EWMH to only show the frames visible on the
current virtual desktop either directly or through GDK.

I noticed that the GTK developer are no no about these kind
information, saying it shouldn't exist in Wayland [1].

Would it make sense to adapt Wayland protocols that don't exist in GTK
in this case? KDE has a protocol[2] for this and Wlroots is considering the 
same,
Compositors such as Swap already having such functionality in their ipc.[3][4]

Br,

Björn
