cool#6893 reduce allocation in ScGridWindow::PaintTile
the code is needlessly allocating way more rows than we need, especially
when we have page to the bottom of a large document.
Make it so we allocate exactly the number of rows we need, instead
of allocating a default large number of rows (1024).
Which reveals that we need to allocate two extra rows, not sure why.
