 When converting a white and red equirectangular image to orthographic
 format, it's unclear where the green pixels in the output image come from.
 Can be reproduced as follows:

 ffmpeg -f lavfi -i color=white:s=400x100 -f lavfi -i color=red:s=400x100
 -lavfi [0][1]vstack,v360=e:og:pitch=90 -frames 1 -y out.png
