Bug:
5520301
When an application requests a row from a SQLiteCursor that
is not in the window, instead of filling from the requested
row position onwards, fill from a little bit ahead of the
requested row position.
This fixes a problem with applications that seek backwards
in large cursor windows. Previously the application could
end up refilling the window every time it moved back
one position.
We try to fill about 1/3 before the requested position and
2/3 after which substantially improves scrolling responsiveness
when the list is bound to a data set that does not fit
entirely within one cursor window.
