Override this function to be notified of any zooming on the displayed bitmap.
A zoom can be requested by the following:
user presses one of the keys defined for zooming
user draws a rectangle while the current tool type is set to TOOL_ZOOMRECT
user clicks the mouse in the class object's window while the current tool type is set to TOOL_ZOOM_ON_MOUSECLICK
If the zoom occurs because the user has zoomed using the TOOL_ZOOMRECT tool, the zoom percent is updated. You can call LBitmapWindow::GetZoomPercent to get the zoom percent currently used to display the image.
