Comment (by Michael Koch):
Replying to [comment:7 Elon Musk]:
> Near interpolation is not proof it needs fix.
Near interpolation? Some pixels are mapped to the wrong octants!
In the dfish2dfish case the vertical line in the left circle is shifted
one pixel to the left.
In the dfish2cyl and dfish2eq cases the error is clearly visible at the
right edge.
In the dfish2ball case the error is clearly visible at the top and bottom.
All these issues can be fixed by subtracting 1 in line 3471.
