2016-11-21	Fix a few cases where pdf_unmark_obj wasn't always being called on errors.	Tor Andersson

2016-02-15	Drop UNUSED macro -- it dirties the namespace and is not needed.	Tor Andersson
	We compile with -Wno-unused-parameters instead.
2015-03-24	Rework handling of PDF names for speed and memory.	Robin Watts
	Currently, every PDF name is allocated in a pdf_obj structure, and comparisons are done using strcmp. Given that we can predict most of the PDF names we'll use in a given file, this seems wasteful. The pdf_obj type is opaque outside the pdf-object.c file, so we can abuse it slightly without anyone outside knowing. We collect a sorted list of names used in PDF (resources/pdf/names.txt), and we add a utility (namedump) that preprocesses this into 2 header files. The first (include/mupdf/pdf/pdf-names-table.h, included as part of include/mupdf/pdf/object.h), defines a set of "PDF_NAME_xxxx" entries. These are pdf_obj 's that callers can use to mean "A PDF object that means literal name 'xxxx'" The second (source/pdf/pdf-name-impl.h) is a C array of names. We therefore update the code so that rather than passing "xxxx" to functions (such as pdf_dict_gets(...)) we now pass PDF_NAME_xxxx (to pdf_dict_get(...)). This is a fairly natural (if widespread) change. The pdf_dict_getp (and sibling) functions that take a path (e.g. "foo/bar/baz") are therefore supplemented with equivalents that take a list (pdf_dict_getl(... , PDF_NAME_foo, PDF_NAME_bar, PDF_NAME_baz, NULL)). The actual implementation of this relies on the fact that small pointer values are never valid values. For a given pdf_obj p, if NULL < (intptr_t)p < PDF_NAME__LIMIT then p is a literal entry in the name table. This enables us to do fast pointer compares and to skip expensive strcmps. Also, bring "null", "true" and "false" into the same style as PDF names. Rather than using full pdf_obj structures for null/true/false, use special pointer values just above the PDF_NAME_ table. This saves memory and makes comparisons easier.
2015-02-17	Add ctx parameter and remove embedded contexts for API regularity.	Tor Andersson
	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.
2013-06-27	Move to using a flags bit rather than "Dirty" dict entries.	Robin Watts
	Correct the naming scheme for pdf_obj_xxx functions.
2013-06-26	Silence compiler warnings.	Tor Andersson

2013-06-25	Rid the world of "pdf_document *xref".	Robin Watts
	For historical reasons lots of the code uses "xref" when talking about a pdf document. Now pdf_xref is a separate type this has become confusing, so replace 'xref' with 'doc' for clarity.
2013-06-25	Update pdf_obj's to have a pdf_document field.	Robin Watts
	Remove the fz_context field to avoid the structure growing.
2013-06-20	Rearrange source files.	Tor Andersson
