   Log Message:
   Update "xpdf" package to version 3.04. Changes since version 3.03:
   - New text extractor.
   - Added the pdftohtml tool.
   - Added the pdftopng tool.
   - New trapezoid-based rasterizer core (for performance).
   - Generate appearance streams for Line, PolyLine, and Polygon
     annotations.
   - Added the closeWindowOrQuit command, and changed the default binding
     for ctrl-W from closeWindow to closeWindowOrQuit.
   - Implemented the new AES-256 mode (R=3D6, Acrobat X).
   - Add an object cache.
   - Added a small cache for object streams.
   - Modify PSOutputDev to use LZW compression instead of RLE, with a
     fallback to RLE if the "psLZW no" setting is given.
   - Pdfinfo now prints page rotation info.
   - Modified ImageOutputDev, used by pdfimages, to output the masks and
     soft masks used when drawing images.
   - Remove non-printable characters from error output, just in case they
     might cause problems for the terminal program.
   - Added initial support for Code3of9 bar codes in XFA forms.
   - Added the mapExtTrueTypeFontsViaUnicode xpdfrc command.
   - Apply stroke adjustment to rectangular images and clipping regions (in
     addition to strokes and fills).
   - Decode JPEG 2000 images at less than full resolution if the full res
     image isn't needed (i.e., if the raw image is higher resolution than
     the output).
   - Implemented knockout groups.
   - Removed t1lib support.
   - Added support for images with 16-bit components.
   - Rewrote the Dict class to use a hash table; as a side effect, this
     handles dictionaries with multiple definitions for a key, which are
     in violation of the spec, but Acrobat appears to handle.
   - The transformed line width computation -- used to implement the
     minLineWidth setting, and the hairline threshold in monochrome mode --
     was incorrect.
   - Pdftops was not correctly handling the case where it couldn't find
     a 16-bit font -- this led to crashes and/or invalid PostScript.
   - A bug in FlateStream::getBlock() was causing problems with narrow
     images.
   - Use the correct _WIN32 define instead of WIN32.
   - Use copy-on-write for the clip path in SplashState (when doing gsave),
     for performance.
   - Added a Solaris-specific entry to the ghostscript font search path.
   - SplashState was initializing line width to 0 instead of 1.
   - Abort processing on a content stream after getting 500 errors
     (undefined operator, wrong number of args) -- this avoids very long
     processing time for malicious PDF files using bogus RLE encoded
     content streams.
   - Added the psUseCropBoxAsPage xpdfrc option; "pdftops -pagecrop" now
     sets psUseCropBoxAsPage; "pdftops -pagecrop -paper match" now uses
     the CropBox as the page size.
   - Re-architected the AcroForm support code into a separate AcroForm
     module.
   - Fixed the handling of overprinting/transparency interaction, using
     the CompatibleOverprint blend mode.
   - The TIFF predictor code for the 1-bit-per-pixel case was broken.
   - For triangle and patch mesh shadings (types 4-7) with color functions,
     interpolate the function parameter not the color.
   - Check the fontFile/fontDir commands before (instead of after) doing
     Base-14 substitution in PS output.
   - Correctly handle non-embedded TrueType fonts that have an Identity
     ToUnicode mapping (display and PS output were failing).
   - Added support for XFA form rendering, including an "enableXFA" xpdfrc
     setting.
   - Handle PFB Type 1 fonts when generating PostScript output.
   - Unwind any extraneous saved graphics state at the end of the page
     (before drawing annotations).
   - Added some integer overflow checks in the GString class.
   - Handle 16-bit components in JPEG 2000 images.
   - ActualText spans can end without a valid font, in which case
     TextPage::beginWord was crashing.
   - The Domain entry in function shadings wasn't being parsed correctly.
   - Fixed a bug in the JPEG decoder - successive approximation
     (progressive mode) coefficients weren't being handled correctly.
   - Added a better infinite loop test to the xref parser.
   - When generating PostScript, merge reused TrueType fonts (if their
     code-to-GID mappings are the same).
   - Tweak the Gouraud triangle shaded fill code to end the recursive
     splitting if the triangles get sufficiently small.
   - Do bilinear interpolation when upsampling images.
   - When skipping extraneous image data from an inline image, look for
     EI<whitespace> instead of just EI.
   - When writing to stdout on Windows, pdftoppm now sets the file mode to
     binary.  [Thanks to Robert Frunzke.]
   - Accept strings as well as names for the BaseFont entry in font
     objects.
   - Removed the TEXTOUT_WORD_LIST config option (with the new text
     extractor, this is always enabled).
   - Fixed a bug in the JBIG2 decoder (the TPGD context for template #3 in
     readGenericBitmap was incorrect).
   - Rewrote the PostScriptFunction code for performance.
   - Handle 8-bit OpenType CFF fonts that are missing required tables in
     the OpenType wrapper.
   - Handle tiling patterns with reversed coordinates in their bounding
     boxes.
   - Added support for 64-bit file offsets, i.e., PDF files larger than
     2GB.
   - Optimize the code that rasterizes pattern-filled image masks.
   - Added support for Mac OS X system fonts (Base-14 only).
   - The backdrop color in luminosity-type soft mask groups was not being
     handled correctly.
   - Modified behavior of "pdftops -paper match -duplex ..." - it will now
     duplex consecutive same-sized pages.
   - Tweak the handling of degenerate fills ('moveto lineto fill') to
     match Adobe.
   - Don't honor the OPM=3D1 setting with ICCBased CMYK color spaces.
   - Whole-word searches were treating certain punctuation (Unicode number
     separators and terminators) as part of the word, e.g., searching for
     "foo" would not match "foo,".
   - Use the TextString class everywhere it makes sense.
   - Removed the unnecessary segment sort in Splash (performance
     optimization).
   - Handle hyperlinks that use Widget-type annotations.
   - Fix up the integer overflow checks to avoid issues with clever
     compilers.  [Thanks to Nickolai Zeldovich.]
   - Correctly handle streams with missing Length entries in damaged PDF
     files.
   - Added a compile-time option (LOAD_FONTS_FROM_MEM) to load fonts from
     memory rather than temporary files on disk.
   - Added the psRasterSliceSize xpdfrc option.
   - Fixed a case in the JPEG 2000 arithmetic decoder where extra data is
     present in packet i, and needs to be saved for use in packet i+1.
   - Fixed a bug in the JPEG 2000 decoder related to images with fewer than
     8 bits per component.
   - Handle the case in PSOutputDev where slice size overflows a 32-bit
     integer.
   - Add (partial) support for TrueType cmap format 2.
   - Always pass FT_LOAD_NO_BITMAP to FreeType -- bitmaps apparently fail
     with rotated characters.
   - Support fonts specified in ExtGState dictionaries.
   - Annotations with empty Border arrays should not draw a border.
   - Fix the CMap parser to handle large CID ranges.
   - Check for Type 3 CharProcs that call q or Q before the d0/d1 operator,
     and treat them as uncacheable.
   - Invert the selection color when starting in reverse video mode.
   - Device{Gray,RGB,CMYK} cannot be mapped via a resource dict.
   - Changed the PS output for masked images (explicit and color key
     masking): use a plain old clip path instead of rectclip to avoid
     array overflows.
   - Check the StemSnapH/V arrays when converting Type 1C fonts to Type 1 -
     if there are any duplicate or out-of-order values, skip that
     StemSnapH/V array.
   - Added the psMinLineWidth xpdfrc setting.
   - Fix an obscure issue in converting TrueType fonts to Type 42, related
     to empty glyph descriptions (12 zero bytes).
   - Pdftops now reports an error if there were any I/O errors writing to
     the PS output file.
   - Fix vertical text (CJK fonts) in PS output -- offset the character
     origin correctly.
   - Increased the number of digits used by pdfimages for the image number
     from three to four.
   - Handle right-to-left (e.g., Arabic) ligatures correctly in the text
     extractor.
   - Added the -loc and -locPS options to pdffonts.
   - Extend the object parser recursion limit to cover Stream::addFilters()
     / Stream::makeFilters() - to avoid another possibility of stack
     overflow.
   - Disable FreeType autohinting, because it can fail badly with font
     subsets that use invalid glyph names -- except in the case of Type 1
     fonts, which look much better with light autohinting.
   - Modified the rasterizer pipeline functions to process a scan line at a
     time (for performance).
   - Removed VMS build support (it hasn't been updated in ages).
   - Removed pdftotext's '-htmlmeta' option (use pdftohtml instead).
   - PSOutputDev's font/form setup code, and pdffonts, were not scanning
     soft mask groups in ExtGState dictionaries.
   - Invalid DCT input (e.g., from a damaged PDF file) could overflow the
     dctClip array.
   - When upsampling an image mask or image with a large resulting image
     size, do it in stream mode instead of prescaling the whole image
     (to avoid running out of memory).
   - Added infinite loop detection to pdffonts.
