known bugs:

* running out of memory (using delay lines or loops) will likely crash pd. 
short story: don't, use pdp_control's memlimit for limiting pdp's memory usage.




todo 0.12.5:

* find nasty 3dp bug
* fix pdp_glx BadMatch bug (crashes on OSX) : fixed in pf
* platform independent [pdp_vdac] [pdp_vadc]
* fix pdp_help_input/output so they are actually usable
* incorporate jamie's osx changes / guenter's windows port



todo later:

* field based bttv capture (might be possible without driver hacks using v4l2)
* pdp_crop/pad
* where to solve autoconvert? per type, or central in pdp_base? 2 cases:
- template based autoconvert: in pdp_base
- compatibility based autoconvert: i.e. pdp_add (solve in base: move_passive)
* finish high level packet conversion:
- move 8bit images to packet level (iow: cleanup pdp_qt, pdp_v4l, pdp_xv) (solve with forth)
- get rid of pdp_type* methods
* fix mac/linux name differences (use pdp_video, pdp_movie, pdp_window)
* pdp_xv framerate doc + pwc addons
* enable audio output on bttv cards in pdp_v4l
* fix cache slicer objects + thread problems (fixed in sliceforth)
* derive as much classes as possible from pdp_base class (obsolete: use forth instead)
* displacement warp, substitution warp, refraction warp, timespace warp, wormhole warp
* check the use of varargs for image processing dispatching routine (obsolete: forth)
* more scopes
* 2D affine transforms parametrized by vectors (center, x-axis, y-axis) (np1 + matrix processing objects)
* some abstractions around pdp_cheby (colour shape, ...)
* efficient rescalers: pdp_double pdp_halve (+ efficient arbitrary scaler in sliceforth)
* move float color conversion and float<->fixed point conv code to system
* crop, shift (pad+scroll)
* solve biquad (blur) mmx boundary init prob (bands at edges: solve with proper init?) (sliceforth)
* optimize blur effect (1 pole ? / dependency stalls) (sliceforth)
* jpeg/png packet and streaming support (pdp_netsend / pdp_netreceive : binary compat issues!!)
* find out why resampling code (warping) is so slow (reg->mem->reg->mem stalls?) (solve in sliceforth)
* mmx profiling (done: sliceforth)
* add audio resampling in pdp_qt~
* use pd_error instead of post for errors
* ascii art packet processors
* 3D time space interpolation
* colour keying
* motion tracking
* moebius transforms
* type multiplexing: find a way to use the same name for packet processors. (solved in forth: polymorhpy)
i.e. pdp_add should add images, but also vectors, ascii packets, textures,...
* modify 2D rotation to be used as arbitrary rotation (givens)
* add 3D rotation
* frame rate limited delay line (burst delay?)
* optimize resampling code (mipmapped packed 16bit format?)
