v0.5: 2002/12/13
first attempt at a documentation (see doc/)
added support for processing in separate lower priority thread
with a packet dropping mechanism to avoid audio dropouts.
added pdp_control object for controlling pdp's scheduling and
detecting packet drops
pdp api cleanup (name changes)
added some more filter abstractions
(motion blur/phase, emboss, sobel, edge)

v0.7: 2003/01/12
moved image format conversion routines to pdp_llconv.c
added support for rgb->PDP_IMAGE_YV12 in pdp_v4l, pdp_qt
added pdp_grey, pdp_chrot, pdp_scope~
moved mmx wrappers to pdp_imageproc_mmx.c
added portable c code in pdp_imageproc_portable.c
added mmx code for pdp_gain
fixed bug in pdp_mix/pdp_mix2
fixed bug in pdp_bq (removed state reset)
moved CA stuff to separate lib (see scaf/)
(0.7.1) fixed rgb colour conversion bug
v0.8: 2003/02/02
added pdp_scale, pdp_zoom, pdp_rotate, pdp_zrot, pdp_scan~, pdp_cheby
added support for 1D ca's + shift compensation in pdp_ca
thread processing is off by default now
added cursor method to pdp_xv, freq method to pdp_v4l (thanks CK)
added pdp_sdl (thanks Martin Pi)
added some example patches in doc/examples
(0.8.1) fixed scaf + gcc<3 compilation problem
(0.8.2) fixed compile prob + added documentation
(0.8.3) completed documentation
v0.9: 2003/02/27
added pdp_scanxy~, pdp_invert
now uses autoconf for configuration
standard "make install" target
optional compililation for external dependencies (xv,qt,v4l,sdl)
experimental OSX port (without i/o)
fixed crash when closing xv window manually
added mouse event output to pdp_xv
pdp_ca now automaticly compiles rule files
fixed image dimension crashes
fixed pdp_xv bang crash
added pdp_grey2mask
added pdp_slice_cut/pdp_slice_glue (experimental/nondoc)
v0.10: 2003/03/06
modules code reorganization
removed pdp_affine object and added compatibility object based on pdp_cheby
added pdp_mchp and PDP_IMAGE_MCHP packet format (experimental)
added pdp_and, pdp_or, pdp_xor, pdp_not, pdp_bitmask, pdp_bitdepth
added base class for pdp objects
added incremental garbage collector
added support for "not so pure" data packets
added opengl subproject containing a pdp_glx display object
added a PDP_TEX opengl texture packet (opengl lib)
added PDP_IMAGE_GREY8, PDP_IMAGE_RGB8, PDP_IMAGE_RGBA8 packets
(0.10.1) fixed (fatal) bug in pdp_base, and bug in pdp_noise (non-mmx)
(0.10.1) pdp_glx now compiles on mac osx
v0.11: 2003/04/08
updated pdp_trigger to behave like pd's trigger object
added automatic philips web cam detection
removed "zombie" packet passing and made pool manager thread safe
(this required an api change: backward compat for pdp thread proc broken)
added gem style object rendering & transformation objects (opengl lib)
removed pdp_gradient binary module (it is now an abstraction)
