  29 // NOTE: We made a concious decision to have only a single 'screen'
  30 // due to the differences in platforms. On Win32 we could gather
  31 // all information, but not for X11 (and possibly Mac). So for now
  32 // we'll stick with a single screen, but the functions are still
  33 // written to support multiple screens, simply beef up the all_screens
  34 // assignment to get multiples
  35 // To support multiples, we need to use GetMonitorInfo API on Win32
