Detailed Description

A HOTSPOT is an object attached to a shape to provide a direct user-interface for implementing custom actions, etc.

Hotspots are clickable areas on a shape indicated by a special "knob" appearance. They can appear anywhere within the bounds. When clicked, they will be tracked and can do any useful thing they wish. The original purpose is to allow the direct manipulation of certain shape parameters such as radius of round corners, and so on, but the design is completely general-purpose.

The action of a hotspot is handled by default by its delegate, though you could also subclass it and implement the action directly if you wish.

The appearance of a hotspot is drawn by default by a method of DKKnob.
