Pi: use vsync by default and fix vsync on case

Browse source 
* Now that vsync off explicitly sets swap interval, it's clear that
  we've been using driver defaults (vsync on) up until now.
* Try to enable normal vsync before late swap tearing. The latter
  doesn't constrain framerate and looks basically identical to vsync
  off.
