* \brief pixItalicWords()
*
* \param[in] pixs 1 bpp
* \param[in] boxaw [optional] word bounding boxes; can be NULL
* \param[in] pixw [optional] word box mask; can be NULL
* \param[out] pboxa boxa of italic words
* \param[in] debugflag 1 for debug output; 0 otherwise
* \return 0 if OK, 1 on error
*
* <pre>
* Notes:
* (1) You can input the bounding boxes for the words in one of
* two forms: as bounding boxes (%boxaw) or as a word mask with
* the word bounding boxes filled (%pixw). For example,
* to compute %pixw, you can use pixWordMaskByDilation().
* (2) Alternatively, you can set both of these inputs to NULL,
* in which case the word mask is generated here. This is
* done by dilating and closing the input image to connect
* letters within a word, while leaving the words separated.
* The parameters are chosen under the assumption that the
* input is 10 to 12 pt text, scanned at about 300 ppi.
* (3) sel_ital1 and sel_ital2 detect the right edges that are
* nearly vertical, at approximately the angle of italic
* strokes. We use the right edge to avoid getting seeds
* from lower-case 'y'. The typical italic slant has a smaller
* angle with the vertical than the 'W', so in most cases we
* will not trigger on the slanted lines in the 'W'.
* (4) Note that sel_ital2 is shorter than sel_ital1. It is
* more appropriate for a typical font scanned at 200 ppi.
* </pre>
