    Issue #5875: Close button too big on wayland backend.
    
    The issue is that on X11, the window manager draws the title bar hence
    uses the window-close button from the system theme, though on Wayland,
    GTK draws its own decorations. Since we provide a window-close, we end
    up with a disparity between this button and the minimize/maximize
    buttons.
    
    For now, let's just get rid of the window-close icon as an easy
    solution, thus GIMP will always use the window-close icon from system
    theme.
    
    Maybe we can restore our own window-close icon later, but we should make
    sure to at least have also window-maximize and window-minimize icons so
    that the 3 buttons next to each others won't look too mismatched. And
    probably we should also have smaller-size design because it doesn't look
    so nice when huge (though it might simply have been the size mismatch
    which gave this feeling).
