Scrolling in the spreadsheet application is linked to cell rows. That is
inconsistent with how scrolling works in every other application, where
scrolling is proportional to the input (degree of mousewheelturn, number of
clicks on scrollbar arrows..).
Try it with a couple of rows with large height. Scroll just a little bit: You
immediately loose track of where you are and how far you just srolled down.
It seems, OO doesn't "want to" show half a cell or something. But the user
should be in control, really.
