//  Class:      IQuadrantEngine (qe) 
// 
//  Purpose:    interface used to communicate to the Quadrant Fractal Engine 
//              Helper 
// 
//  Interface:  Init             -- initializes the object (call first) 
//              UseBoundingBoxes -- enables/disables bounding box optimization 
//              SetGraphSize     -- tells the engine how big the graph is 
//              Start            -- starts the engine 
//              Stop             -- stops the engine 
//              Reset            -- tells the engine restart drawing the graph
