Subject: [PATCH] - API/CLI/Tcl/GUI: new output option
 BARCODE_BIND_TOP/`--bindtop`/   `-bindtop`/"Bind Top" - DPD: add top boundary
 (width 3X) by default, using new   BARCODE_BIND_TOP; "relabel" option; some
 compliance checks - GUI: only skip encoded/errored signal processing if
 active modal   ExportDialog (wasn't clearing/setting error text bar correctly
   for DataDialog) - CODE128: debug print checksum -
 CODE49/DATAMATRIX/QR/ULTRA: fix uniqueness of errtxt nos - manual: fuller DPD
 doc; some spelling typos, formatting

+Another variation of Code 128 as used by DPD (Deutscher Paketdienst). Requires a
+27 or 28 character input. For 28 character input, the first character is an
+identification tag (Barcode ID), which should usually be `"%"` (ASCII 37). If
+27 characters are supplied, `"%"` will be prefixed by Zint (except if marked as
+a "relabel", see below). The rest of the 27-character input must be
+alphanumeric, and is of the form:
+
+Destination Post Code  Tracking Number     Service Code  Dest. Country Code

+
+Table: {#tbl:dpd_input_fields tag=": DPD Input Fields"}
+
+A warning will be generated if the Service Code, the Destination Country Code,
+or the last 10 characters of the Tracking Number are non-numeric.
+
+Zint formats the Human Readable Text as specified by DPD, leaving out the
+identication tag, and adds a modulo-36 check character to the text (not to the
+barcode itself), thus:
+
+`PPPP PPP TTTT TTTT TTTT TT SSS CCC D`
+
+By default a top boundary bar is added, with default width 3X. The width can be
+overridden using `--border` (API `border_width`). For a symbol with no top
+boundary bar, explicitly set the border type to bindtop (or bind or box) and
+leave the border width 0.
+
+A DPD Code can be marked as a "relabel" by specifying `--vers=1` (API
+`option_2 = 1`), which omits the identification tag and prints the barcode at
+half height. In this case, an input of 27 alphanumeric characters is required.
