gdkwindow: Apply the 0x0 size bump to 1x1 before checking for the bail

Browse Source 
Otherwise, a user that calls gdk_window_resize (window, 0, 0); over and
over won't properly fizzle out, and will queue a redraw. Clipped, but
still. These redraws can be chatty on some platforms like Wayland, and
there's no good reason to not avoid them.

This was the case for resize grips.
