`PlaneDetectorEXT::getPlaneDetectionStateEXT` still broken

[jherico]

The enhanced function contains this code

  XrPlaneDetectionStateEXT state_tmp;
  PlaneDetectionStateEXT state;
  Result result = static_cast<Result>(
      d.xrGetPlaneDetectionStateEXT(this->get(), state_tmp));

But the dispatcher call here expects a XrPlaneDetectionStateEXT* as it's second argument, not a XrPlaneDetectionStateEXT.

This may also apply to Session::thermalGetTemperatureTrendEXT. This is the only other function I can find which has an output enum type.

I don't get why extension authors seem to be avoiding the convention of "Everything is wrapped in an extensible structure", especially with the above thermalGetTemperatureTrendEXT where it has 3 output pointers being passed instead of a single output structure pointer. That means the C++ code ends up looking more like C code because you can't do an enhanced foo = session.thermalGetTemperatureTrendEXT() with the signature like it is.

Although I see your name is on XR_EXT_performance_settings so sorry if that's your design I'm complaining about.

The thermal stuff is ancient, as old as basically anything else in the spec. Most new stuff is nearly going too far in the direction of everything in a struct. :)
