  3152. ;; | 15.27.28 Overflow behavior
  3153. ;; |
  3154. ;; | For text boxes contained within text document, the

  3156. ;; | boxes where the containing text does not fit into the text
  3157. ;; | box.
  3158. ;; |
  3159. ;; | If the attribute's value is clip, the text that does not fit
  3160. ;; | into the text box is not displayed.
  3161. ;; |
  3162. ;; | If the attribute value is auto-create-new-frame, a new frame
  3163. ;; | will be created on the next page, with the same position and
  3164. ;; | dimensions of the original frame.
  3165. ;; |
  3166. ;; | If the style:overflow-behavior property's value is
  3167. ;; | auto-create-new-frame and the text box has a minimum width or
  3168. ;; | height specified, then the text box will grow until the page
  3169. ;; | bounds are reached before a new frame is created.
  3170. ;; `----
  3171. ;; Unfortunately, LibreOffice-3.4.6 doesn't honor
  3172. ;; auto-create-new-frame property and always resorts to clipping
  3173. ;; the text box. This results in table being truncated.
