1. Use a faster scroll speed under X11 …

   Platforms may report scroll deltas either in
   chunks/lines/rows or pixels, depending on the
   platform API and device capabilities.
   
   If the platform reports a line/chunk-based delta
   then the application needs to convert the delta
   into a suitable number of pixels.
   
   This commit just hardcodes it to 57 as
   a starting point which matches the value that
   Firefox calculates as the max char height
   for the root frame on my system.
   
   Fixes #5660
