For the record, when scrolling on the page on a 10,000 * 100 table with overflow: hidden, the painting used to take ~255 ms (for 2048 x 256). We are now down to ~45 ms.

Painting has been sped up but the core issue still remains: we should have visit only the visible cells instead of all the cells in the table.
