--- Comment #1 from V Stuart Foote <vstuart.foote at utsa.edu> ---
+1, reasonable but why just for spreadsheets, and why only cursor up/down
scroll moves why not for <pgUp>/<pgDwn> or the scrollbar 'thumb' widget moves?
Calculate where the canvas will end up after the buffered movements and only
draw that. Kind of the antithesis to 'smooth scroll'
