* This is done by first checking if the *first* row is NULL. If so,
* we move the viewport *forward*, until the first row is non-NULL. At
* this point, the entire viewport should be allocated rows only.
*
* If the first row already was non-NULL, we instead check the *last*
* row, and if it is NULL, we move the viewport *backward* until the
* last row is non-NULL.
