immediate plan:

	* design gui for editor
	* libfontfocus
	* write mupdf hackers guide
	* clean up and 'freeze' public api

	* get font bbox from fontdescriptor if available
	* refactor image loading
	* refactor xref loading/repair
	* restructure build.c and interpret.c (ftb vs csi)
	* fix the colorspace/pattern/shading material mess
	* font loading:
		- configuration... where to find system files (asian font archive?)
		- system fontfile + cmap store
		- embedded fontfile store
		- split type3 and ftfont malloc (dont waste t3 charprocs on ft fonts)
		- make ftfontfile separate struct w/ refcounting
		- refactor font loading more. simple/cid/type3 have too much in common.

	* structure low/high level stuff
		- rewrite outline parser
		- implement comments

	* clean high-level api

	- go through spec and check all features!
	- altivec optimize

std rsrc fmt (v3)

transparency (v2)
	- everything!

colorspace conversions (v2)
	- fast color cubes
	- proper colorspace conversions
	- gamut compression
	- extended render intents

image rendering (v2)
	- tiles
	- dct case
	- better filter than box
	- lazy decoding

rendering
	- fix glyphcache evictlast
	- bbox culling per glyph
	- font focus
	- render cache (link-nodes and scaled images and colorspaced shades)

fz_optimizetree()
	- error & memory
	- concatenate chained transforms
	- remove identity transforms

for filters:

	validate ahxd pushback
	go through eof responsibility
	be more defensive of api user errors
	flate needin/needout

	jbig2 rewrite
	dctencode params
	dctdecode app marker
