I wrote a small program that does:

        XFixesHideCursor( dpy, DefaultRootWindow( dpy ) );

and that does not do what my -nocursor patch does. I still see the cursor
over an applications window. Are you expecting that I have to hunt
down every windows on the screen and call hide on it?

Also When I call:

        XFixesShowCursor( dpy, DefaultRootWindow( dpy ) );

I get:

xfixes example
XFixesQueryExtension => 1
    event_base: 113
    error_base: 180
XFixesQueryVersion => 1
    major_version: 4
    minor_version: 0
XFixesShowCursor
