We pack the mask type and the color parameters into a byte. We
were unpacking it incorrectly, resulting in all masks being
treated as luminosity ones.

1) Reset the margins at the start of each PCL job to avoid offsetting
the page contents.
2) Fix height/band_height confusion in mono band writing.

Writing to wide format output was causing uncompressed lines of
more than 32K to be written to a 32K buffer.
I now recognise that there is an inherent limitation in PCL where
image data can't be larger than 32K, so we'll have to split
page output into subimages and hope they register well enough.
This new commit does that (and solves the overwrite). I am seeing
problems when feeding the output from this into gpcl due to the
delta compression. We believe this is a bug in gpcl, and is being
investigated as bug 699969.

Was set to create an exe rather than a lib. For some reason this
didn't upset VS2005, but did upset VS2008.

The filter op for Tz was reading the scale in and dividing by 100 as we
do elsewhere. The buffer op was then forgetting to multiply by 100
before rewriting it.

Pull in the latest changes from mainline lcms2, and bugfixes from
gs. This should now be the definitive version.

This makes it easier to test failure inside
the succeeding fz_try().

The exception is still thrown, however. This just
ensures that CMM is not left in an unknown state.

By setting ctx->cmm_instance == NULL we actively made sure that
fz_cmm_fin_profile() would never call ->fin_profile() to actually
clean up the ICC profiles.
This could be triggered by doing mutool draw -N even without a
file name, triggering a memory leak.

Also save history when glut closes the window or otherwise exits the
main loop.

This release includes the auto-generated ragel files, so we don't need
to use the Artifex branch anymore.

Drop the unused 'serif' argument to the CJK lookup functions.
Use the BCP 47 names for CJK scripts and languages:
zh-Hant for traditional Chinese,
zh-Hans for simplified Chinese,
ja for Japanese,
ko for Korean.
The lookup function also allows commonly used language+country codes:
zh-TW and zh-HK for traditional Chinese,
zh-CN for simplified Chinese.

Don't bother compiling the freetype C files that are #included by ftbase.c
This fixes a harmless "repeated symbol" warning in the windows build.

Using #ifdef FZ_ENABLE_ means we build code in, even if we have
defined FZ_ENABLE_WHATEVER to be 0 (as we do in config.h).

MuPDF may attempt to load a page but fail to do so, e.g. due to
a circular page tree. When this happens the page will never be
introduced into the document's list of pages. Its next and prev
pointers are both NULL, but the code in fz_drop_page() falsely
assumed that the prev pointer was always set.
Thanks to oss-fuzz for reporting.

Keep a list of currently open pages for each document. Attempting to
load a page that is already loaded will return the same instance again.

There is a regression for 2325_-_JPX_image_with_padding_rejected.pdf.
Object 3 in that document is a JPX-encoded image. Its EOC marker is
preceded by two extra bytes of data, 0x80 0x80. This makes the file
broken according to the JPEG 2000 specification.
Acrobat Reader and the Kakadu JPX decoder accepts this file without
issues, so OpenJPEG 2.1.0 added code to fix this (bug 226, commit
005e75bdc). That fix detects exactly two bytes of 0x80 0x80, a rather
brittle fix. Adding more padding or changing the padding byte values
is not accepted. Adding more padding is acceptable to Acrobat Reader
and Kakadu. An unrelated fix for another problem has since broken
OpenJPEG's support for this broken image.

This removes the need for unistd.h, which isn't around on
VS2005.
Also remove unused variable.

The upsampling code in the JPX decode attempted to guess a
suitable upsampling factor. The guessed factor was wrong,
causing writes of samples outside of the decoded image buffer.
Simply limiting the coordinates to the image buffer would
not suffice because the factor was wrong for every upsampled
row of pixels. openjpeg does provide an upsampling factor,
so use that instead and also take the component offsets into
account when decoding components into the pixmap. Combined
this resolves the issue that previously triggered ASAN.
Thanks to oss-fuzz for reporting.

pdf_page_transform() may throw due to a cycle in the page tree.
When this happened mupdf would previously forget to drop the
default colorspaces obtained, after this commit they are dropped.
