This is faster on ARM in particular. The primary changes involve
fz_matrix, fz_rect and fz_bbox.
Rather than passing 'fz_rect r' into a function, we now consistently
pass 'const fz_rect *r'. Where a rect is passed in and modified, we
miss the 'const' off. Where possible, we return the pointer to the
modified structure to allow 'chaining' of expressions.
The basic upshot of this work is that we do far fewer copies of
rectangle/matrix structures, and all the copies we do are explicit.
This has opened the way to other optimisations, also performed in
this commit.
Rather than using expressions like:
fz_concat(fz_scale(sx, sy), fz_translate(tx, ty))
we now have fz_pre_{scale,translate,rotate} functions. These
can be implemented much more efficiently than doing the fully
fledged matrix multiplication that fz_concat requires.
We add fz_rect_{min,max} functions to return pointers to the
min/max points of a rect. These can be used to in transformations
to directly manipulate values.
With a little casting in the path transformation code we can avoid
more needless copying.
We rename fz_widget_bbox to the more consistent fz_bound_widget.

MuPDF needs access to the original file when saving, and in any case
directly overwritting the original file has much more potential for
data loss than use of a temporary file.

Only Fade, Wipe and Blinds supported so far.
Hit 'p' in the viewer to go into 'presentation' mode. Page swaps
then transition from page to page. Pages auto advance until key
or mouse is used.

Currently the app windows app responds with a message box explaining that
the MuPDF library passes print requests to the app, but the app does not
implement printing.

Rather than having a dedicated call to enumerate the rectangles for the
annotations on a page, add an interface for enumerating annotations
with accessor functions. Currently the only accessor function is
the one to get the annotation rectangle.
Use this new scheme in place of fz_bound_annots within mudraw.
Also use this scheme to set the caret cursor in the viewer when over
a data field.

This is initialised to rgb or bgr according to whether _WIN32 is set
as has always been the case. This allows apps that want to override
it (such as mujstest) to do so though.

Simple command line tool made from cutting all the windows specifics
out of win_main.c and adding a simple script handler in.
Read lines from the script, and feed those events to pdfapp. Screenshot
pages as required.

The file supplied with the bug contains corrupt jpeg data on page
61. This causes an error to be thrown which results in mudraw
exiting.
Previously, when image decode was done at loading time, the error
would have been thrown under the pdf interpreter rather than under
the display list renderer. This error would have been caught, a
warning given, and the program would have continued. This is not
ideal behaviour, as there is no way for a caller to know that there
was a problem, and that the image is potentially incomplete.
The solution adopted here, solves both these problems. The fz_cookie
structure is expanded to include a 'errors' count. Whenever we meet
an error during rendering, we increment the 'errors' count, and
continue.
This enables applications to spot the errors count being non-zero on
exit and to display a warning.
mupdf is updated here to pass a cookie in and to check the error count
at the end; if it is found to be non zero, then a warning is given (just
once per visit to each page) to say that the page may have errors on it.

Use _wopen on a UTF8 -> wchar_t decoded filename to support UTF8 filenames
for win32.

Use 'i' to toggle inversion of the rendered MuPDF bitmap, giving
simple 'white on black' mode.

Toggle with 'f'. Fullscreen turns off shrinkwrap, and shrinkwrap turns
off fullscreen.

Move coordinate space tweaks into pdf_ and xps_run_page, and provide
neutral pdf_ and xps_bound_page functions to return the page size as
a zero-origined bounding box.

Move to a non-pdf specific type for links. PDF specific parsing is
done in pdf_annots.c as before, but the essential type (and handling
functions for that type) are in a new file fitz/base_link.c.
The new type is more expressive than before; specifically all the
possible PDF modes are expressable in it. Hopefully this should
allow XPS links to be represented too.

Mostly redoing the xps_context to xps_document change and adding
contexts to newly written code.

Huge pervasive change to lots of files, adding a context for exception
handling and allocation.
In time we'll move more statics into there.
Also fix some for(i = 0; i < function(...); i++) calls.

Added BEYOND_TRESHHOLD for pdfapp and code which flips to next/previous
page if one pans beyond the page end plus that threshhold.

The run-together words are dead! Long live the underscores!
The postscript inspired naming convention of using all run-together
words has served us well, but it is now time for more readable code.
In this commit I have also added the sed script, rename.sed, that I used
to convert the source. Use it on your patches and application code.
