gdk_x11_display_set_window_scale() affects the interpretation of the Xft/DPI XSETTING - it is substituted inside GDK with the value of Gdk/UnscaledDPI xsetting. However, this change is not propagated to GTK+ and from GTK+ back to gdk_screen_set_resolution() until the main loop is run. Fix this by handling the screen resolution directly in gdk/x11. This requires duplication of code between GDK and GTK+ since we still have to handle DPI in GTK+ in the case that GdkSettings:gtk-xft-dpi is set by the application. https://bugzilla.gnome.org/show_bug.cgi?id=733076
