Hi!

The povray 3.5 manual states, that the number of intervals in media 
defaults to 10, but I believe it defaults to 1 instead. Is this an error 
in docs or am I missing something? This also causes some problems with 
Moray - basically you can't use interval with value 10.

Example:

box {
     <-10,-2,-10>, <10,10,10>
     pigment {rgb 1}
     interior {
         media {
             scattering {
                 1, rgb 0.055
             }
         intervals 10 // Removing this line _does_ make a difference
         }
     }
     hollow
}

PS. If there is a list of bugs etc. please let me know.

The relevant part POV-Ray 3.5 manual was originally written for v3.1, when
method 1 was the only available media sampling method. When it was updated
for 3.5, that section was not made clear that what it was talking about is
no longer the default sampling method - the default is now method 3, and the
documentation mostly talks about method 1. (Discussion about methods 2 and 3
are further down on the same page, I think.)

Add "method 1" to your code and you will probably get the default 10
intervals.

This is an area of the documentation which could be improved to avoid
misunderstandings like this.
