Detailed Description

Draw handler.

A draw handler allows the application programmer to add custom behavior associated with the window drawing. To use a draw handler, declare a derived class that implements the OnDraw method, then link it to the viewer using SetDrawHandler. The OnDraw method will be called after the window is drawn at every rendering cycle.
