       This module attempts to extract sequential text from a PDF page.  This is not a robust process, as PDF
       text is graphically laid out in arbitrary order.  This module uses a few heuristics to try to guess what
       text goes next to what other text, but may be fooled easily by, say, subscripts, non-horizontal text,
       changes in font, form fields etc.

       All those disclaimers aside, it is useful for a quick dump of text from a simple PDF file.

       $pkg->render($pagetree)
       $pkg->render($pagetree, $verbose)
           Turn a page content tree into a string.  This is a class method that should be called like:

              CAM::PDF::PageText->render($pagetree);
