I rendered the beautiful illustrations from the demo scene file 
i_internal.pov, but I got tired of having to go back and forth between 
the illustrations and the scene file to see which function was 
represented by a given illustration.  So I modified i_internal.pov to 
render the name of the function into the image.  The modified file is 
attached.

There are two issues with the header comments.  First, the creation date 
is ambiguous.  Second, there is a character in the original author's 
first name that my text editor (kwrite) cannot figure out.  A hex dump 
shows the character as 0x8E, which is an illegal character in Unicode 
and, as far as I can tell, in all ISO Latin character sets.  Some 
research and a bit of serendipity revealed that it is the Windows-1252 
character capital Z with a caron.  Is this correct?
