Taking into account that the label does not use the full circumference 
of a cylinder. I created a CSG intersection and tried to map that. I 
found it very difficult to get the scaling right. My usual method of 
doing this is to pad the outside of the image with a transparent colour 
so that there are no transformations to worry about. Only working out 
the size of the image within an image. I've never been happy with doing 
that, though.

So I used a bi-cubic patch and planer mapping, that worked better.

I would like to see an example using cylindrical mapping so that image 
was fully visible on only part of the surface.
