//
// If we were to call Bitmap.GetHbitmap, we'll get back an HBitmap that
// is intended for 32-bit displays.
//
// MMC expects the HBITMAP it gets to be compatible with the screen. So,
// if the current video display is not set to 32 bit, MMC will fail to show the bitmap.
//
// So what do we do? We translate the bitmaps into the color depth that the screen
// is currently displaying
