  • format grid: option headerless for reading any kind of file
  • format grid: option headerful (revert to actual .grid format mode)
  • fixed problems with GNU C++ version 3
  • format ppm: accelerated writing
  • format modifier gzfile: gzip support also works with [@out]
  • format x11: the “here” specifier is now optional
  • added @checkers
  • [@scale_by {y x}] for different y,x scale factors
  • [@in blah blah] means “open blah blah” -> [@in] (and same with @out)
  • added @downscale_by with or without smoothing
  • format targa: can now decode 32 bit RGBA
  • @layer: combines RGBA foreground with RGB background, yielding RGB.
  • format grid options: endian big, endian little, endian same

    (by default, rewind is no longer done after each frame)
    (‘option rewind’ also rewinds on reading)
