* 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)
