* Routine update
* Incorporated 1 security patch from the xpdf homepage
Added the continuous view mode, including the '-cont' switch and the
'continuousView' config file option.

Support explicitly masked images and soft masked images.
Add support to DCTStream for 16-bit quant tables.
Don't segfault if the user clicks on an outline entry with a broken

Fixed a bug handling empty paths.
Fixed a text positioning problem in PostScript output.
Handle TrueType collections in FoFiTrueType.cc.
FoFiTrueType constructor was reporting a failure if the post table was
bad - this should be non-fatal.

Mask chars passed to isdigit in goo/parseargs.c to avoid problems with
Added more error checking to the CCITTFax decoder.
Fixed a bug (computing the MCU size) in the DCT decoder.

Implement the remaining shading types (4-7).
Rearranged the Splash color modes.
Add the EarlyChange parameter to LZWStream when generating PostScript.

standard name-to-Unicode mapping before the ToUnicode mapping
defined in the font object.
Added a matteColor setting (command line option and X resource).
Tweaked the CMYK->RGB transform.
Fix some problems in tracking the character position (to match up with
Adobe's highlight file format).
Handle moveto/closepath/stroke correctly.
Check for singular text matrices and font size of zero in PSOutputDev.
Clip PS output to the size of the page (avoiding any gibberish that
lies outside the MediaBox, in the case where the MediaBox is smaller
than the paper).
If the line dash element in an annotation's Border array is of an
invalid type (i.e., not an array), don't draw the link at all (this
matches Adobe's behavior).
Don't remap small caps and oldstyle glyphs in the name-to-Unicode
table - it messes up TrueType font encodings.
Pdftoppm wasn't setting the paper color correctly in mono and gray
modes (this only showed up on big-endian machines).
Missing NULL check was causing crashes when attempting to read non-PDF
files that happened to contain the string '%PDF'.
Fixed a problem in the text extractor that was breaking up words.
Handle vertical text (CJK fonts) in PS output with TrueType fonts that
are missing the vertical metrics tables.
Handle the case where a font object and the corresponding embedded
font are different types.
Handle basic crypt filter functionality.
Added more value checking in the XRef parser, to avoid potential
Updated the CJK language support packages: replaced the
displayCIDFontX references with displayCIDFontTT; added pointers to
free TrueType fonts.
Added a missing error message when SplashOutputDev can't parse an
embedded TrueType font file.
PDFCore and TextOutputDev now correctly handle searching for Unicode
strings, including real Unicode case-folding.
Throw away tiling pattern fills that are completely outside the clip
The JPEG 2000 inverse reversible multiple component transform code was
Fixed some bugs in shading pattern fills: clipping was wrong, and
background color was not implemented.
Added tool tips for the toolbar buttons.
Decrease the max depth of recursive patch mesh filling if the pattern
has a large number of patches.
Highlight the find text whenever the find dialog is mapped.
Handle page boundary boxes with reversed coordinates.
Fixed a bug in the text extractor code that handles duplicated text.
Optimization work on SampledFunction::transform().
Use the CropBox instead of the MediaBox as the display region.
Dither for PseudoColor (8-bit) displays.
Fix a bug in DCTStream that was causing an infinite loop with
corrupted DCT image data.
Fix a bug in the ToUnicode CMap parser.
Fix a bug in the text extractor - negative font sizes weren't being
Fix a bug in the text extractor - in certain cases, out-of-bounds text
could cause crashes (generally only in damaged PDF files).
Fix a read-past-end-of-array bug in the JBIG2 decoder.
Fix a case where pdftops was generating lines longer than 255 chars.
Optimize redraws - don't regenerate the XImage every time redrawRect
The ASCII85 decoder wasn't skipping whitespace properly.
Optimize text extraction: skip (non-inline) image setup entirely.
Added initial transparency support (stroke/fill alpha and blend mode).

in cases of mixed horizontal and vertical text).
PSOutputDev wasn't rounding the page bounding box coordinates
Support the SOF1 marker in DCT (JPEG) image streams.
Minor changes to GlobalParams.h and JPXStream.h because some compilers
don't like anonymous structs inside anonymous unions.
Xpdf now complains about a negative page number.
Changed GString::cmp and GString::cmpN to correctly handle '\0' chars
in the middle of strings.
Corrected the handling of the 'extend' parameters in radial shadings.
Added the gmallocn and greallocn functions.
Fixed a bug in the TIFF image component predictor which shows up with
components that are not 1 or 8 bits wide.
For non-embedded Base-14 fonts, don't use the ascent/descent/bbox
values from the FontDescriptor - various PDF generators get them
Fixed a bug in the text extractor - words on the same line (especially
in tables) were being split vertically onto multiple lines.
Automatically select the correct radio button ("print with command"
vs. "print to file") in the print dialog.
Don't create the "open" and "save as" dialogs until needed - this
avoids stat-ing every file in the directory at startup.

language support package) to include characters from the Unicode
database (which aren't mentioned in the Adobe character collection
Added the '-pagecrop' switch to pdftops.

same embedded 16-bit TrueType font, but with different CIDToGIDMaps.
Changed the configure script to report more accurate warnings when
it can't find X / Motif / FreeType.
Encryption with revision=2 always uses a 40-bit key, regardless of the
specified Length value.
Yet another minor change to the TrueType font encoding deciphering
Don't completely invalidate the Catalog if one (or more) of the page
objects are bogus -- just skip over those pages.
Removed the workaround in pdftops for too-small Length2 values in Type
1 fonts -- it was causing problems on various PostScript printers.
Started adding error checking to the JBIG2 decoder (this is nowhere
near complete yet).
Extended the "unicodeToUnicode" config option to also apply to CID
Added the narrow Latin characters to the Adobe-Korea1.cidToUnicode
file in the Korean language support package.
Fixed the code that handles page rotation in PSOutputDev.
When converting a Type 1C glyph to a Type 1 glyph, insert closepath
operators as appropriate.
