Set width, height to 1 to avoid mmap fails

Hi,

As I was trying some samples(caret and controls) of wxWidgets on Wayland, I met
this error at launch:

"(controls:2962): Gdk-CRITICAL **: gdkwindow-wayland.c:578: mmap'ping temporary
file failed: Invalid argument"

It comes from gdk_screen_get_root_window() which returned a GtkWindow with
height and width set to 0.

But GtkWindow
doc(https://developer.gnome.org/gtk3/3.5/GtkWindow.html#gtk-window-set-default-size)
indicates that it should be set to 1. I did that it fixes my issue.

The patch joined corrects the bug.
