The patch on macOS and under XQuartz (X server on macOS)
has the consequence that both wheel and shift-wheel have the same
effect: the vertical scrollbar is activated, and no effect on the
horizontal scrollbar.

That is expected because without the patch, shift-wheel was 
treated by the OS as a horizontal move.
