IIRC, I wrote this. Most sensors have a a few more lines and columns of pixels
than their nominal resolution. The extra pixels are used to simplify the bayer
decoding algorithm. There are also optical black pixels, used in black level
compensation. So the "10" is here to position the "window of interest" at the
center of the pixel matrix.
The formula would be better like this : rowstart =
(matrix_height-window_height)/2
