Neither one is right.  Consider this scene:

camera
{
  location  0
  direction z
  angle 120
  ultra_wide_angle
}

light_source { 0 color rgb 1 }
  
#declare i=0;
#while (i<360)    
  sphere { 40*z, 1 rotate i*y texture {pigment {color rgb 1}}}
  sphere { 40*z, 1 rotate i*x texture {pigment {color rgb 1}}}
  sphere { 40*z, 1 rotate i*x rotate 45*z texture {pigment {color rgb 1}}}

  #declare i=i+10;
#end

The superpatch renders this with what looks like an angle of 160, while
the official version renders it at 100.  I haven't investigated why there's
a difference yet.
