Data[4]...Data[7] = double word Ysize : describes the “height” of the window (y axis).
Xsize, Ysize are given in “pixels”
Xsize and Ysize determine the size of the window, since the aspect ratio is fixed, one of the values may be
sufficient to determine the size of the window.
If the 2 values do not match the aspect ratio, then Xsize is taken as reference and Ysize is calculated to match
the aspect ratio.
