You can use image with 'once', scale it down to fit your section unrolled into
<0,0,0>-<1,1,0> area, and then use spherical warp. Then you can duplicate
sections with layered textures. Similiar method was recently described by me in
a thread: http://news.povray.org/povray.newusers/31686/ with working example. I
hope it could work for you.
