 When converting from equirectangular to fisheye, the output image is
 shifted about one pixel to the right. The same problem is also in dfisheye
 output. Can be reproduced as follows:

 ffmpeg -f lavfi -i color=white:s=100x25 -f lavfi -i color=red:s=100x25
 -lavfi [0][1]vstack,v360=e:fisheye:pitch=90 -frames 1 -y out.png
