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.

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).

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.

This was used to prevent infinite cycles in the Type3 font CharProcs,
but the previous commits forbids all cycles in order to prevent memory
leaks due to cyclic reference counts.

Use separate functions to keep the code simpler.
Use memmem to simplify and optimize search for 'endstream' token.
Do not look for 'endobj' since that could cause a false positives in
compressed object streams that have duff lengths.

Always look for the "endstream" marker after a PDF stream to see
if we've hit the end. Allow for "endobj" to cope with producers
that omit endstream entirely.
Avoid slowing down legal files by only checking for the end marker
after the specified length has been read.

Create a matrix that transforms a page with resolution and rotation,
and grid fits the resulting bounding box.

Several things irk me about passing values as const pointers:
* They can be NULL, which is not a valid value.
* They require explicit temporary variables for storage.
* They don't compose easily in a legible manner, requiring
weird pointer passing semantics where the variable being assigned
is hidden as an argument in the innermost function call.
* We can't change the value through the pointer, requiring yet more
local variables to hold copies of the input value.
In the device interface where we pass a matrix to a function, we often
find ourselves making a local copy of the matrix so we can concatenate
other transforms to it. This copying is a lot of unnecessary busywork
that I hope to eventually avoid by laying the groundwork with this
commit.
This is a rather large API change, so I apologize for the inconvenience,
but I hope the end result and gain in legibility will be worth the pain.

Updates the input point coordinates, and also returns a quad with
appropriate UI handles.

The Noto symbol font has been split into two. The second symbol font only
contains a subset of the emojis, so reinstate the real emoji font and add
both symbol fonts to the fallback chain.

Remove the mutiff document type.

Return TTC subfont index from fz_lookup_noto_font.

Force the face_flags to include TRICKY if we detect a DynaLab font
name instead of trying to force hinting ourselves.

If Bitmap.lockPixels fails with an allocation error, scavenge in
the store.

Ken reports that a VS2008 import of the projects fails with
complaints about __restrict whereever stdlib.h is included.
Fix the #ifdeffery so that we don't mess with it on VS2008.

_WIN32 is always defined on windows (it means the WinAPI is available).
_WIN64 is also defined on 64-bit targets.
This means the test for defined(_WIN32) || defined(_WIN64) is redundant,
since if _WIN64 is defined, then _WIN32 is always also defined.
MSC_VER is only defined for MSVC, so split the ifdef sections in
include/fitz/system.h into separate MSVC and WIN32 parts so that
we can build with MinGW and other non-MSVC compilers on windows.

In the absence of C99 (fz_rect){0,0,1,1} syntax, this will have to do.

Call these from the PDF interpreter. Make the DisplayList and
Trace devices cope.
Use these in the SVG output device.
|

Use a FZ_PRINTFLIKE macro instead.

This is needed to simplify the way the bytes for hashing are
passed to pkcs7 functions.

This provides a way for some output streams to also be read, a feature
needed for the sake of document signing. Currently this is supported only
for file output.
