Move the definition of fz_font to be in a private header file
rather than in the public API. Add accessors for specific
parts of the structure and use them as appropriate.
The font flags, and the harfbuzz records remain public.
This means that only 3 files now need access to the font
implementation (font.c, pdf-font.c and pdf-type3.c). This
may be able to be improved further in future.

To be moved into a new document writer interface later.

The scissor argument is an optional (potentially NULL) rectangle
that can give hints to devices about the area that can be scissored.
This is used by the draw device and display list device to minimize
the size of temporary clip mask buffers.
The scissor rectangle, if used, must have been transformed by the
current transform matrix.

Image objects are immutable and opaque once constructed.
Therefore there is no need for the const keyword.

Shading objects are immutable and opaque once constructed.

MSVC doesn't understand %04X. Use %04x instead.

It's an opaque immutable structure, that we don't expect to ever want
to change after creation. Therefore the const keyword is not useful,
and is only line noise.

In general, we should use 'const fz_blah' in device calls whenever
the callee should not alter the fz_blah.
Push this through. This shows up various places where we fz_keep
and fz_drop these const things.
I've updated the fz_keep and fz_drops with appropriate casts
to remove the consts. We may need to do the union dance to avoid
the consts for some compilers, but will only do that if required.
I think this is nicer overall, even allowing for the const<->no const
problems.

We can now group all clipped text into one fz_text object and simplify
the device interface.

Use fz_output in debug printing functions.
Use fz_output in pdfshow.
Use fz_output in fz_trace_device instead of stdout.
Use fz_output in pdf-write.c.
Rename fz_new_output_to_filename to fz_new_output_with_path.
Add seek and tell to fz_output.
Remove unused functions like fz_fprintf.
Fix typo in pdf_print_obj.

Firstly, we make the definition of the path structures local to
path.c. This is achieved by using an fz_path_processor function to
step through paths enumerating each section using callback functions.
Next, we extend the internal path representation to include other
section types, including quads, beziers with common control points
rectangles, horizontal, vertical and degenerate lines. We also roll
close path sections up into the previous sections commands.
The hairiest part of this is that fz_transform_path has to cope with
changing the path commands depending on the matrix. This is a
relatively rare operation though.

Purge several embedded contexts:
Remove embedded context in fz_output.
Remove embedded context in fz_stream.
Remove embedded context in fz_device.
Remove fz_rebind_stream (since it is no longer necessary).
Remove embedded context in svg_device.
Remove embedded context in XML parser.
Add ctx argument to fz_document functions.
Remove embedded context in fz_document.
Remove embedded context in pdf_document.
Remove embedded context in pdf_obj.
Make fz_page independent of fz_document in the interface.
We shouldn't need to pass the document to all functions handling a page.
If a page is tied to the source document, it's redundant; otherwise it's
just pointless.
Fix reference counting oddity in fz_new_image_from_pixmap.
