Detailed Description

A view to display a Dimmer Curve and allow a user to edit.

If the curve is editable it will be displayed with the control points selectable by the mouse, and the user will be able to drag the points into new positions. The lookup table of the curve is updated when editing ends (that is when the user releases the mouse).

You can set a delegate object that may implement a number of hooks into the drawing and editing routines associated with this class.
