//After some experiment, I did some improvements.
//1.I found that instead of 1/3 of the frame is shown, I got 3 whole frames shrinked into one window.
//So I made the height twice simply by painting 2 identical lines in the place of original lines
//2.I found sometimes there is an horizontal offset, so I added x_correction to move the frame back to center manually
//3.I changed video_buffer's type, from ui::Color to uint_8, since I don't need 3 digit to represent a grey scale value.
//I was hoping that by doing this, I can have a longer buffer like 39936, then the frame will looks better vertically
//however this is useless until now.
