Docs could be clearer, yes. Too bad I suck at docs or I'de throw
something together for the pov-team to use. Just experiment with
an easily-recognizable image and you'll get the hang of it.
To rotate an image around a lathe, translate the image in the
x direction. The total uv width (and height) of the image is
always 1 (before translation. etc.) so translate in 0.1
increments and re-render to see what is going on. In the uv-
coordinate space, X and Y are the coordinates you are wanting
to play with. translating or scaling Z will have no effect.

Ok: if you are using UV_mapping just to put a logo on a coffee
cup then you can use an easier way. If you use a cylindircal
mapping on the image map, life will be easier. The "map_once"
option plus careful scaling and translation will get that logo
where you want it on the cup. The only bad side to useing a
cylindrical map is that the logo will also appear on the inside
of the cup. Careful camera placement is most likely enough
to fix that. :)
