 /**
  * A class for storing a composite color transformation. All the
  * transformations added with appendTransform() are applied
  * sequentially to the process pixels.
  *
  * \p mode defines how the buffers are used while processing.
  *
  * When using INPLACE mode all transformations but the first one do
  * the conversion in place, that is in \p dst buffer. That is \p dst
  * is written at least N - 1 times, where N is the number of embedded
  * transformations.
  *
  * In BUFFERED mode all the transformations are called with distinct
  * src and dst buffers, which are created in temporary memory owned by
  * KoCompositeColorTransformation. Please note that this mode IS NOT
  * IMPLEMENTED YET!
