* Handle generator transforms (plugins whose channel count isn't dependent on number of audio inputs, as they have none) * Be less keen to suspend writing FFT data in spectrogram repaint -- only do it if we find we actually need to query the FFT data (i.e. we aren't repainting an area that hasn't been generated at all yet)
