		    _find_pdf_mime_parts(), resulting in no detection of pdf mime parts.
		  - quoted-printable support - requires	MIME::QuotedPrint (which should	be in everyones
		    install as a part of the MIME-Base64 package which is a SA req)
		  - added simple pdf_is_empty_body() function with counts the body bytes minus the
		    subject line.  can add optional <bytes> param if you need to allow for a few bytes.
	      0.5 - fix	warns for undef	$pdf_tags

		  - added option to look for image HxW on same line
	      0.3 - added 2nd fuzzy md5	which uses pdf tag layout as data
		  - renamed pdf_image_named() to pdf_named()
		     - PDF images are encapsulated and have no names.  We are matching the PDF file name.
		  - renamed pdf_image_name_regex() to pdf_name_regex()
		     - PDF images are encapsulated and have no names.  We are matching the PDF file name.
		  - changed pdf_image_count() a	bit and	added pdf_count().
		     - pdf_count() checks how many pdf attachments there are on	the mail
		     - pdf_image_count() checks	how many images	are found within all pdfs in the mail.
		  - removed the	restriction of the pdf containing an image in order to md5 it.
		  - added pdf_match_details() function to check	the following 'details'
		     - author: Author of PDF if	specified
		     - producer: Software used to produce PDF
		     - creator:	Software used to produce PDF, usually similar to producer

	      0.2 - support PDF	octet-stream
	      0.1 - just ported	over the imageinfo code, and renamed to	pdfinfo.
		    - removed all support for png, gif,	and jpg	from the code.
		    - prepended	pdf_ to	all function names to avoid conflicts with ImageInfo in	SA 3.2.
