Resize the cell buffer. Existing contents will be preserved,
provided that they still fit. Contents that no longer fit will
be clipped (lost). Newly added cells will be initialized to empty
content. The entire set of contents are marked dirty, because
presumably everything needs to be redrawn when this happens.
