Same as a call to txTextAddFlowPlus in which the pages parameter is set to DV_NULL.
Each texflow area created by this function is always placed on its own page in the text document. The first textflow area (area with index 0) is placed on the first page (page with index 0), the second textflow area (area with index 1) is placed on the second page (page with index 1), the third textflow area (area with index 2) is placed on the third page (page with index 2) etc.
