//
//there is a small BGU, mainly is to capture the mouse pointer image without considering the current background color, is black all the time,
//updated to intercept the mouse pointer to the current picture will use the current background color fill background, if you do not specify a background color in
//use the white (RGB (255255255)) filling,
//
//on July 10, 2011 update:
//
//add a CopyFormBitmap in TBDBitmapData class members, this function can be from TBitmap object
Copy//copy the picture, you can specify the location of the picture, size,
