I did make an nxn table of kerning values. There are 82 characters in my
character set so it took a long time to do by hand. Later I did think of a way
to automatically generate the kerning values. Unfortunately, the method I
thought of relied on CSG intersections and the min_extent () and max_extent ()
functions. It did not work properly. I consulted the documentation and found the
following message regarding these functions:

Note: This is not perfect, in some cases (such as CSG intersections and
differences or isosurfaces) the bounding box does not represent the actual
dimensions of the object.

So if you can fix POV-Ray's min_extent () and max_extent () functions to work
with CSG intersections or think of a work-around, here's a macro to compute
kerning values. Good luck!
