Actually I just noticed that the mesh2 object supports specifying a
texture index for each face separately. So, the functionality is already
there and it shouldn't be too hard to extend the output of the surf2pov
function with color information.

In order to still retain control over other aspects of the texture
the exported texture list could call a FACE_TEXTURE(COLOR) macro that
needs to be defined by the scene prior to #including the data.

As far as I see only two of his images are tagged with povray and those
do not look like precolored meshes.

One of the problems may also be that your requirements are still a
bit vague. The Julia reference from your first post is quite a different
beast than a colored mesh plot.
