** k2pdfopt_proc_one() is the main source file processing function in k2pdfopt.

**
** The basic idea is to parse the source document into rectangular regions
** (held in the BMPREGION structures) and then to place these regions into
** the master destination bitmap (kept track of in MASTERINFO structure).
** You can think of this bitmap as a sort of "infinitely scrolling" output
** bitmap which is then cut into output pages.
**
** The bmpregion_source_page_add() function parses the source file.
**
** The masterinfo_publish() cuts the output bitmap into destination pages.
**
** If rot_deg == SRCROT_AUTO, then the rotation correction of the source
** file is computed and returned, but no other processing is done.
**
** Otherwise, the source file is processed.
