+# Tests that the following works, both on Wayland and X11
+#  1. Create a window with a known size
+#  2. Maximize window results in maximized size
+#  3. Fullscreen window results in fullscreen size
+#  4. Unfullscreen window results in maximized size
+#  5. Unmaximize window results in original size
+#  6. Toggling fullscreen ends up with original size
