"""eval_final.py (imported, NOT modified) with every appearance comparison done at 512x512.

The only change: eval_final.appearance_metrics(pred_rgba, ref_rgba) -- called once per IV / NV view with the masked
crops -- now receives both images composited over white (exactly as appearance_metrics does internally) and resized
to 512x512 (cv2 INTER_AREA when downsampling, INTER_LINEAR when upsampling), passed on as opaque RGBA.
Rendering, masks, coverage, view selection and geometry are unchanged.
Usage: python eval512.py fb150   <eval_final.py args>
       python eval512.py rest658 <eval_rest658_wrapper.py args>
