Changes since last version:1.1o Fixed -dither color option to find best 24 bit or greater visual  for most machines.o Fixed recursive loop in Makefile. o Added entries for R6000 and SGI's in Makefileo Fixed declaration of j_rev_dct.o Does initial sequence start code check to confirm validity of mpeg stream.o Changed or's in ordered dither to add's to allow more flexible  allocation of color ranges.o Uses shared memory.o Lots of little bugs fixed.1.2o Fixed shared memory problem (freeing memory twice on exit).o Added entries for Sony NEWS machineso Added monochrome support.o Unrolled loops for optimization.o Variety of small bugs.2.0o Added ability to use private colormap.o Display name can now be given as part of command line.o Fixed green artifacts problemo Fixed sequence end code cutoff problem.o Lots of performance tweaks.o Other bugs.2.1o Fixed frame dropping problem.o Supports MPEG system layer (tosses audio)o 16, 32 bit color modes (thanks to: Erik Corry erik@kroete2.freinet.de)o Added -owncm to guarantee a private colormapo Added gray256 to get 256 shades of grey (and added gray/grey no diff)o Fixed leaving of shared memory buffers when shared memory crashes  (in the common case of running from the wrong display)o Instructions for IRIX4 Cflags in PLATFORMS.o Added -step, -start, and -endo Fixed insanely subtle readfile bugo Added color2 true color doubling dither, provided by garyo@avs.com (thanks!)o Added ppm dither, provided by Jef Poskanzer <jef@acme.com> (thanks!)o Added bzero.c for silly SOLARISo -no_display doesnt put up a window now.o -gamma float, raises the luminance of each pixel to float (a   floating point number),  thus -gamma 0.8 darkens, -gamma 1.2 lightenso Fixed ycc to rgb conversion block assignment mixup.  (thanks to John Toebes <toebes@unx.sas.com> for pointing this out)o Added frame rate limiting (-framerate)o Doesn't skip initial B frames (after an I) if the GOP is closed.o Auto-determines RGB order of server (well, RGB vs BGR anyway).o Fixed a few grainy blocks appearing due to bugs in sparse IDCT function.o -nop now implies -nob (doesnt make sense to have B's w/o P's)o -seek indexes into fileso Added chroma averaging in color and color2 dithers (thanks to	tristan@tcela.la.tce.com (Tristan 'RAMBO' Savatier))o Added -quality option, which, when turned on,   o correctly implements halfpel motion vector averaging  o uses a very time-consuming but accurate IDCTo Sped up player a little by using lookup tables for y/cr/cb valueso Minor, unreported bugs.2.2o added controlbar (thanks: "Michael J. Donahue" <donahue@ulexite.nist.gov>)o made -step work AFTER the picture displayo made default state be to play the video (in control panel)o fixed bug in -start w/o -endo fixed color equn's more (thanks tristan@cauliflower.la.tce.com (Tristan 'RAMBO' Savatier))o made INTERPOLATE the default in color2o made gamma_correction abstracted and in greyscale too, (thanks Tristan)o made includes happier for VMS2.3o added -position (thanks to jingo@VNET.IBM.COM)o fixed bug in parseblick.c, lower bit of level handled wrongo extensive changes in moving variables around to make as a  reentrant library (thanks to Loring Holden <lsh@cs.brown.edu>)o added (then removed) -xid to have it play in an established window.  Doesn't seem to work with the reentrant changes.  Ideas anyone?o -ppm{width,height,skip} for scaling/subsampling in 	-dither ppm (thanks legalize@xmission.com)o -nob bug fixedo now skips until it finds a start code...  Slower on bad files (like    mpeg_play /kernel   but works with sliced up MPEGso -no_display / -dithe rppm fixed (Jason Patterson <jason@reflections.com.au>)
