Bug#350292: Please also use shift-wheel to scroll left or right

["James R. Van Zandt" <jrvz@comcast.net>]

I would also like shift-wheel to scroll left or right, as in evince or
inkscape.  That is, I would like the default resource

   xdvi.wheelTranslations:\
   Shift<Btn4Down>:left(.08)\n\
   Shift<Btn5Down>:right(.08)\n\
   Ctrl<Btn4Down>:set-shrink-factor(+)\n\
   Ctrl<Btn5Down>:set-shrink-factor(-)\n\
   <Btn4Down>:wheel(-.7)\n\
   <Btn5Down>:wheel(.7)
