  A warp is basically a transformation (linear or non-linear; it doesn't
matter with textures) which can be applied in a chain of other transformations
and this order will be preserved (unlike eg. 'turbulence' which does not
preserve the order in which it was given relating to other transformations;
hence 'turbulence' and 'warp { turbulence }' are two different things).

  In this case the warp transformation is useful exactly because it
preserves the order of the transformations: The image is scaled *first*
and *then* a spherical transformation is applied to it.
