Synopsis:         High-level interface to FFTW (Fast Fourier Transform) based on comfort-array
Description:
  FFTW claims to be the fastest Fourier Transform in the West.
  This is a high-level interface to @libfftw@.
  We re-use the type classes from @netlib-ffi@.
  .
  Features:
  .
  * Support of one (audio), two (image), three (video) dimensional data,
    as well as n-dimensional one.
  .
  * Support for batched transformations e.g. for block-wise Fourier transform.
  .
  * No normalization like in plain @fftw@.
    This is because I see no universally best place to apply normalization.
  .
  The use of @comfort-array@ enables to use array shapes tailored
  to Fourier transforms:
  .
  [@Shape.Cyclic@]: for data where the @n-1@-th element
  can also be accessed via index @-1@.
  [@Shape.Half@]: for complex data of a real-to-complex Fourier transform.
  It saves you from case distinction between even and odd data length
  and according mistakes.
  [@Shape.Symmetric@]: for real-to-real Sine and Cosine transforms.
  They assert that you will always use
  the appropriate kind for back transformation.
  .
  For rather simple examples
  see the packages @align-audio@ and @morbus-meniere@.
  .
  See also package @fft@.
