Identical shape to SpectrogramPluginOptions minus the fields that only make sense in
'full' mode ('rendering' itself is forced to 'windowed' below; frequenciesDataUrl/autoGain
have no windowed equivalent - see their doc comments on SpectrogramPluginOptions;
maxCanvasWidth only applies to full mode's fixed-size canvas pagination). Field names and
semantics are otherwise byte-for-byte what the pre-unification WindowedSpectrogramPlugin
accepted.
