x11: Copy from actual window, not parent

This code is a relic from GTK2 days and should not be necessary anymore,
as code now makes sure to only copy those parts of the window that are
not overlapped by parent windows.

By deleting it we fix potential issues with composited and translucent
windows copying the wrong data.
