* Add plugin parameter dialog, and use it to set up parameters for feature extraction plugins via a semi-opaque (translucent?) configurationXml string which is associated with a given transform instance. This is not yet saved to and restored from the SV file properly. * Remove no-longer-relevant BeatDetect and BeatDetectionFunction transforms (replaced a long time ago with the beat detector plugin).

Chris@0 26 * Extracted into a standalone Qt3 widget by Pedro Lopez-Cabanillas
Chris@0 27 * and adapted for use in QSynth.

Chris@0 45 * AudioDial is a nicer-looking QDial that by default reacts to mouse

Chris@0 48 * left to decrement it. AudioDial also responds to the mouse wheel.

Chris@0 50 * The programming interface for this widget is compatible with QDial,

Chris@0 52 * colour and a boolean property mouseDial that determines whether to
Chris@0 53 * respond to radial mouse motion in the same way as QDial (the
