Comment 1 Sam Lantinga 2018-01-03 18:05:42 UTC 
Does this patch give negative values for scrolling up and left and positive values for scrolling right and down?
Comment 2 Sam Lantinga 2018-01-03 18:34:54 UTC 
Sorry, the y should be flipped in my description:
    Sint32 x;           /**< The amount scrolled horizontally, positive to the right and negative to the left */
    Sint32 y;           /**< The amount scrolled vertically, positive away from the user and negative toward the user */

I'll assume that you corrected the values to match the above and commit your patch.
