%  MIFFtoSTEREO combines two images and produces a single image that is the
%  composite of a left and right image of a stereo pair.  The left image is
%  converted to grayscale and written to the red channel of the stereo image.
%  The right image is converted to grayscale and written to the blue channel
%  of the stereo image.  View the composite image with red-blue glasses to
%  create a stereo effect.
%
%  Command syntax:
%
%  export left_image.miff right_image.miff stereo_image.miff
%
%  Specify 'left_image.miff' or 'right_image.miff' as '-' for standard input.
%  Specify 'stereo_image.miff' as '-' for standard output.

X  o When displaying a composite MIFF image created with `montage',
X    button 3 no longer displays a magnify window.  Instead the
X    tile at the mouse location is displayed.  When the tile image is
X    exited, the composite image reappears.  This is effectively a
X    visual image directory.
X
X  o `montage' has a new gravity option for placing an image within
X    a tile of the composite, i.e. CenterGravity.
X
X  o `montage' has a new compose option for specifying which composite
X     operation to use.
X
X  o `montage' creates composite images with the `montage' keyword.
X
X  o Updated MIFF manual page to reflect 'montage' image header
X    keyword.
X
X  o Some compilers have read-only strings.   ImageMagick no longer
X    writes on read-only strings.
X
X  o For colormapped X servers, the color reduction has been sped up by
X    trading image quality for processing time.  See the README for
X    details.
X
X  o Latin1Upper was declared wrong in X.h.
X
X  o Added unistd.h to display.h for strict ANSI compilers.
X
X  o Changed long to time_t for calls to C time routine.
X
X  o Multi-part GIF's can now be displayed or animated.
X
X  o Fixed segmentation fault when reading multi-part images with
X    animate, montage, or mogrify.
X
X  o Multi-part MIFF images have the correct file name now.
X
X  o An expose event for the Magnify window may occur before it is
X    mapped.  This caused display to fail on Solburne and HP's.
X
X  o Using `-colorspace gray' with 'convert' correctly produces
X    grayscale images.
X
X  o Images are sorted by intensity for shared colormapped visuals.
X    Some intensity intervals are made "more popular".  This gives better
X    image results when sharing colors with other applications.
X
X  o All utilities correctly read multi-part TIFF images.
X
X  o Image pixmap was not being updated correctly when pan icon appears
X    (thanks to [e-mail]).
X
X  o Fixed ANSI warning on image composite code.
X
X  o Panning uses a pixmap for faster panning speed.
X
X  o Rotate.c now uses a table to force range limits.
X
X  o Fixed strcasecmp to work under VMS.
X
X  o range table in quantize.c is allocated from the heap instead of
X    the stack.
X
X  o adjusted the sensitivity for automatic dithering.  Some JPEG images
X    were not being dithered.
