Make slowness of attribute lookups more apparent in grid sample

Browse Source 
Multiply the number of rows in the grid sample by a factor of 10. This
demonstrates the slowness with attribute lookups better when using
checkered (Ctrl+Shift+K) or coloured (Ctrl+Shift+L) cells, as filling
the grid is slowed down by way more than a factor of 10. Scrolling also
becomes less responsive the further away from the home cell the view is.

As a result of increasing the row count also move the cells positioned
near the end of the grid there again, and don't use fixed coords for
them.
