func Preflight() error

Preflight fails outside an X11 session: x11grab cannot capture Wayland.

func WindowBounds(_ context.Context, window string) (display.Region, error)

WindowBounds returns the frame (decorations included) of the matching top-level window, preferring the topmost one.

type Screen struct {
	Width, Height             int
	NativeWidth, NativeHeight int
}

Screen is the primary display: its logical size and the size in pixels the platform screen grabber captures (larger on scaled/HiDPI displays).

func PrimaryScreen(context.Context) (Screen, error)

PrimaryScreen returns the X11 root screen, which x11grab captures 1:1. It is read from X directly: robotgo's purego build targets Wayland.
