What about reading the documentation ?
Especially the sub-...-chapter about spherical projection in Pov-ray
Reference/Scene Settings/Camera/Types of projection.
(That should be 3.3.1.2.8 of the windows documentation, just launch
povray, hit F1 and there you are!)

So, I believe:
(1) Yes
(2) At worst, you could look at the code of the relevant camera.
