title: Can I assume that on android SDL registers main screen as touch device 0? Or else how do I get main screen id?
body: <p>As <code>SDL_GetNumTouchDevices()</code> suggests, SDL supports multiple touch devices.</p>
  
  <p>Can I assume that <code>SDL_GetTouchDevice(0)</code> will return an ID of the main screen?</p>
  
  <p>If I can't then how do I figure out which one of them is the main screen?</p>
