/**
	Provide two-way communication between application and library.
	Intended for multi-threaded applications where one thread is
	rendering pages and another thread wants to read progress
	feedback or abort a job that takes a long time to finish. The
	communication is unsynchronized without locking.

	abort: The application should set this field to 0 before
	calling fz_run_page to render a page. At any point when the
	page is being rendered the application my set this field to 1
	which will cause the rendering to finish soon. This field is
	checked periodically when the page is rendered, but exactly
	when is not known, therefore there is no upper bound on
	exactly when the rendering will abort. If the application
	did not provide a set of locks to fz_new_context, it must also
	await the completion of fz_run_page before issuing another
	call to fz_run_page. Note that once the application has set
	this field to 1 after it called fz_run_page it may not change
	the value again.

	progress: Communicates rendering progress back to the
	application and is read only. Increments as a page is being
	rendered. The value starts out at 0 and is limited to less
	than or equal to progress_max, unless progress_max is -1.

	progress_max: Communicates the known upper bound of rendering
	back to the application and is read only. The maximum value
	that the progress field may take. If there is no known upper
	bound on how long the rendering may take this value is -1 and
	progress is not limited. Note that the value of progress_max
	may change from -1 to a positive value once an upper bound is
	known, so take this into consideration when comparing the
	value of progress to that of progress_max.

	errors: count of errors during current rendering.

	incomplete: Initially should be set to 0. Will be set to
	non-zero if a TRYLATER error is thrown during rendering.

/**
	The store can be seen as a dictionary that maps keys to
	fz_storable values. In order to allow keys of different types to
	be stored, we have a structure full of functions for each key
	'type'; this fz_store_type pointer is stored with each key, and
	tells the store how to perform certain operations (like taking/
	dropping a reference, comparing two keys, outputting details for
	debugging etc).

	The store uses a hash table internally for speed where possible.
	In order for this to work, we need a mechanism for turning a
	generic 'key' into 'a hashable string'. For this purpose the
	type structure contains a make_hash_key function pointer that
	maps from a void * to a fz_store_hash structure. If
	make_hash_key function returns 0, then the key is determined not
	to be hashable, and the value is not stored in the hash table.

	Some objects can be used both as values within the store, and as
	a component of keys within the store. We refer to these objects
	as "key storable" objects. In this case, we need to take
	additional care to ensure that we do not end up keeping an item
	within the store, purely because its value is referred to by
	another key in the store.

	An example of this are fz_images in PDF files. Each fz_image is
	placed into the	store to enable it to be easily reused. When the
	image is rendered, a pixmap is generated from the image, and the
	pixmap is placed into the store so it can be reused on
	subsequent renders. The image forms part of the key for the
	pixmap.

	When we close the pdf document (and any associated pages/display
	lists etc), we drop the images from the store. This may leave us
	in the position of the images having non-zero reference counts
	purely because they are used as part of the keys for the
	pixmaps.

	We therefore use special reference counting functions to keep
	track of these "key storable" items, and hence store the number
	of references to these items that are used in keys.

	When the number of references to an object == the number of
	references to an object from keys in the store, we know that we
	can remove all the items which have that object as part of the
	key. This is done by running a pass over the store, 'reaping'
	those items.

	Reap passes are slower than we would like as they touch every
	item in the store. We therefore provide a way to 'batch' such
	reap passes together, using fz_defer_reap_start/
	fz_defer_reap_end to bracket a region in which many may be
	triggered.
