Subject: [PATCH] When moving by long distances (whole screenfuls) via API
 setCenter calls, reinitialize the grid. This solves an 'infinite loop' like
 problem where if you jumped by a long way, where addColumn/addRow were simply
 looping for so long that the browser went unresponsive/broken. Fixes issue
 reported by NickH on users list as well.
