When "angle" keyword within camera statement appears after "panoramic" keyword
then looks like ignored. But when it is present before "panoramic" then it not
allow values larger then 180 (bouce of perspective limitation). As I understand
documentation both are possible - angle > 180 for panoramic and/or angle after
projection type. Is it my misunderstand, bug within documentation or bug within
povray ?

And what direction is angle defined for panoramic? Vertical or horizontal?

I can confirm on POV-Ray 3.5 beta 7, Win98SE, Athlon 700, 192MB

IIRC, it has worked for me in the past.  However, testing on both Megapov 0.7
and POV-Ray 3.1g fails as well.

I don't think putting the angle *before* panoramic should necessarily work -
POV-Ray doesn't know yet that the camera will accept angles > 180.  However,
putting it after should work as the documentation describes.  However, it
appears to have no effect.  Using direction does work.  Of course, I'm not as
sure of what values to use for direction...
