-/* A knob exposes a binding for some float in a module's context
- * which can be varied at runtime between frames to influence
- * the output.  There's some overlap with settings, but settings
- * are more intended for configuration applied at context
- * creation, which won't vary frame-to-frame, but may influence
- * the initial value and/or automatic behavior of knobs for
- * instance, or even which knobs are available.
- *
- * At this time knobs will only apply to floats, accompanied by
- * some rudimentary bounds.
- *
- * Integer types would probably be useful, and maybe a precision
- * specifier, those can be added in the future as needed, but I'd
- * like to keep it simple for now and see what kind of problems
- * emerge.
- *
- * The current expectation is that a module context struct will
- * incorporate an array of knobs, replacing loose floats already
- * being automatically varied within the module frame-to-frame.
- *
- * The module will then use the knob_auto_* helpers below to
- * access and manipulate the values, instead of directly
- * accessing the loose floats as before.
- *
- * External manipulators of the knobs will use the knob_*
- * helpers, instead of the knob_auto_* helpers, to
- * access+manipulate the knobs.  These helpers are basically just
- * to get external and internal manipulators to agree on which
- * side owns control via the managed field.
