Access to physical monitors

[lasnikr]

This is a question / feature request. I am looking for low level components that allow access to the count of physical monitors and access to move a window to a certain monitor.
My goal is to have a window on each monitor in fullscreen mode. I know that GTK 3/4 and SDL2 do provide the possibility to do this but I would love to do it in a seemingly more pure way.

I searched through the code and came to the conclusion that it is extremely unlikely that this is possible (is it even possible to have multiple windows, startApp doesn't sound like it should be called more than once?), but maybe it is possible or there is a way to access SDL2 directly.
