// CChartViewer / CViewPortControl Implementation
//
// The CChartViewer	is a subclass of CStatic for displaying	chart images. It extends CStatic 
// to support to support alpha transparency image maps clickable hot spots with tool tips 
// zooming and scrolling and image update rate control. The CViewPortControl is a subclass of 
// CStatic for visualizing and supporting interactive control of the CChartViewer viewport.
//
// To use these controls in a dialog in the Dialog Editor drag a Picture control （CStatic
// control） to the form configure its type as “Bitmap“ and give it a unique ID. Then right 
// click on the control and add a variable to represent the control using CChartViewer or
// CViewPortControl as the variable type.
