Overview
~~~~~~~~

fft_dit_1ch template specialization for single (monolithic) FFT, window API

Window interface FFT graph is offered with a single input windowed, ping-pong buffer. Window interface FFT implementation does not support parallel computation (TP_PARALLEL_POWER = 0 only). However, dynamic point size is available (TP_DYN_PT_SIZE = 1), which allows a window buffer size to be an integer multiple of the FFT's point size ( TP_WINDOW_VSIZE = N * TP_POINT_SIZE). Feature offers performance improvements, particularly with small FFT graphs.
