For a program that reopens its windows where they were:
x()/y()give the top left of the current window's frame, in logical pixels from the top left of the main display.set_position(x, y)moves the frame there, unless nothing of it would show on a display (a display that was unplugged since). On macOS the displays come fromNSScreen.screens: winit'savailable_monitors()came back empty here, becauseCGGetActiveDisplayListfailed. Elsewhere they come from winit.set_size(w, h)sizes the drawable. On macOS the size changes at once with noResizedevent, so the new size is recorded, the surface reconfigured, andresized()reports it.Checked on macOS with two displays: a window moved to (120, 140) and sized to 500x260 reads back as 120,140 at 1000x520 physical. Moving it to (-99999, 140) leaves it in place. Moving it to (-100, -1000) puts it on the display above.
