If glxgears is started on a bare X server without a window manager, it does not get a ConfigureNotify event. This means that the only time the viewport is initialized is in main, when it calls reshape(winWidth, winHeight). This does not take the size mangling caused by -fullscreen into account, so the gears appear in a 300x300 box in the lower-left corner of the window instead of filling the window as intended.
Fix this by moving the size override from make_window to main, and pass the overridden size to both make_window and the initial reshape.
