I consider this a bug. An unintended limitation, technically. It's easy
enough (by adding 6 lines of code) to allow all warps (including turbulence
warps) to be applied to textures using texture{texturename modfiers}.
Currently, only transformations can be applied. We probably never want to
allow just plain 'turbulence', but putting turbulence in a warp is easy to
do and should be allowed.
