------------------
Added the continuous view mode, including the '-cont' switch and the
'continuousView' config file option.
At high zoom levels, don't rasterize the entire page - this avoids
problems running out of memory.
Added "search backward" and "match case" options to the find dialog.
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
destination.
Changed the makefiles and configure script to skip building pdftoppm
(in addition to xpdf) if X, Motif, or FreeType is not found; changed
the error message in the configure script to match.
Move an inline function in JArithmeticDecoder.cc to avoid compiler
errors.
Fixed a bug in the rasterizer that was sometimes causing infinite
loops with round line caps on vertical lines.
Various rasterizer optimizations.
Look for intermediate resize events - try to avoid lagging when the
user is doing an opaque resize.
The FormType key in Form XObjects is optional.
Handle external 16-bit TrueType fonts correctly, using the Unicode
cmap.
Add class declarations to TextOutputDev.h to work with stricter C++
compilers.

Changes:
- s/USE_X11BASE/USE_X11/
- fix paths in manual pages
- install shared directory for supplemental packages
2.02:
=====
- Rewrote the text extractor code that assembles words into lines to
better handle vertically overlapping lines.
- Add the "match" option for paper size (in PostScript output).
- Added support for external 16-bit TrueType fonts; added the
displayCIDFontTT and displayNamedCIDFontTT commands to the xpdfrc
file.
- Added an Arabic language support package.
- Added the Windows-1255 encoding to the Hebrew language package.
- A missing NULL check was causing a crash when closing the file in a
single window (which clears out the window, but leaves it open).
- Deal with TrueType fonts whose glyph data is out of order - this
affected both FreeType rasterization and PostScript generation.
- Munge font names in PSOutputDev to avoid names that are problematic
for ghostscript because they start with an out-of-limits number
(e.g., 1e999foo).
- Modify the TrueType font encoding deciphering algorithm in yet another
attempt to match up with Acrobat's behavior.
- Bounds check the indexHigh value in indexed color spaces.
- The text extractor no longer bothers trying to get an average
character width for Type 3 fonts, since it generally doesn't work
very well (because Type 3 metrics are unreliable).
- Don't crash if the user hits ctrl-G ("find again") before doing a
find.
- Set the button pixmap foreground color correctly.
- Handle text drawn backward on 180 degree rotated pages.
- Added a magic call to XtUngrabButton after calling XmCreatePopupMenu
which appears to prevent some very odd problems (idea taken from the
DDD source code).
- Fix the MacOS X fix (needed to include <AvailabilityMacros.h>).
- Fixed a bunch of Motif 1.x / X11R5 incompatibilities. [Thanks to
William Bader and Albert Chin-A-Young.]
- Fixed various bugs in previously untested code in the JBIG2 decoder.
- Modify the XPDFCore destructor to avoid a bogus warning message from
OpenMotif 2.2.
- Modified the Type 1C font parser to do proper bounds checking.
- Fixed the bounds checking in the TrueType font parser.
- Text extractor shouldn't do block merging in physical layout mode.
- Fixed a problem in PSOutputDev in level2sep mode with images in a
Separation color space and with a non-default Decode array.
- Text extraction with "-raw" was concatenating lines from the bottom
of one column and the top of the next.
- Handle Type 1C subroutines in the font converters.
- Correctly handle progressive JPEG images whose scans are slightly
different sizes (e.g., the Y scan rounds up to a multiple of 8
pixels and the Cb/Cr scans round up to 16 pixels).
- Avoid a potential divide-by-zero problem in TextOutputDev.
- Modified the T1Font and FTFont modules to correctly handle glyphs that
are larger than the font's claimed bounding box.
- Tweak dupMaxDeltaX parameter in TextOutputDev to avoid triggering on
double characters.
- Improved detection in pdfinfo for ISO paper sizes. [Thanks to Hartmut
Henkel.]
- Xpdf wasn't responding to the TARGETS atom, which prevented pasting
the selection into various applications. [Thanks to Phillip Ezolt.]
- Handle XObjects with recursive references in their Resources
dictionaries (in PSOutputDev).
- Change PSOutputDev to deal with invalid PDF files that use
non-embedded TrueType fonts with no encoding.
- Check for undersized Widths arrays in fonts.
- Add bounds checking code to Array class.
- Updated VMS build scripts. [Thanks to Martin Zinser.]
- Tweak the TrueType font handling code (again):
- char codes in symbolic fonts may or may not be offset by 0xf000
- discard empty tables because they sometimes confuse FreeType
- Fixed bounds checking in the Flate decoder.
- Removed a bogus error message for exponential functions without
explicit C0/C1 values. [Thanks to Hartmut Henkel.]
- Handle the other Unicode cmap type (platform=0) in TrueType fonts.
- Added support for the SGI Motif horizontal paned window widget.
[Thanks to Felix Ritter.]
- Ignore extra elements in link destination arrays.
- Accept external Type 1 font files with a suffix of ".ps" or no suffix
at all.
- Add a bounds check in the DCT decoder.
- Added instructions for building xpdf.exe under cygwin/XFree86.
