This may be causing me problems then, I added the close root call to work around
minglx's single window support.

from glitztest.c....

  glitz_glx_close_root(dpy, screen);

  if (!onscreen_format) {
    printf ("no onscreen format found\n");
    exit (1);
  }


void glitz_glx_close_root(Display *display,
                           int screen) 
{
  glitz_glx_screen_info_t *screen_info =
    glitz_glx_screen_info_get (display, screen);
    
  XDestroyWindow (display, screen_info->root_drawable);
  
  screen_info->root_drawable = None;
}
