/* The Libogc bounding box in smoothed IR coordinates is 232,284 792,704. However, there is no
   universal standard that works with all games. They all use their own calibration. Also,
   there is no widescreen mode for the calibration, at least not in the games I tried, the
   game decides for example that a horizontal value of 500 is 50% from the left of the screen,
   and then that's the same regardless if we use the widescreen mode or not.*/
