    Description

      https://stackoverflow.com/questions/16840312/stretchblt-doesnt-create-a-mirror-image

      StretchBlt(pdc, 0, h, w, -h, dc, 0, 0, w, h, SRCCOPY);
      must do mirroring (flip vertically).

      StretchBlt creates a mirror image of a bitmap if the signs of the nWidthSrc and nWidthDest parameters or if the nHeightSrc and nHeightDest parameters differ.
