20030723 Released version 0.0.a11
    -   Changed default install prefix to /usr so the gimp plugin is
        found automagically
    -   Fixed some non-C (that recent versions of gcc nonetheless accept)
    -   User can select rectangular regions on plugin preview window
        (press and drag with button 2)
    -   Can calculate white balance using region selected as above
    -   Can crop preview and loaded image to region selected as above

20030707 Released version 0.0.a10
    -   Improved autoconf behaviour
    -   Preview generation is non-blocking
    -   Progress bar showing status of preview generation
    -   Minor changes to parameters don't reset preview zoom
    -   Automatically use different d7i WhitePoint
    -   Code cleanup and bug fixing

20030228 Released version 0.0.a9
    -   Changed preview to use a back-ported eye-of-gnome viewer.  You
        can have large previews with reduced CPU power required.
    -   Presets (daylight, cloudy etc.) are now obtained from the MRW file,
        since they seem to be very camera dependent.
    -   -dx option deprecated in favor of -scale option.  You can now scale
        by any even factor.
    -   Added -xvmini flag to generate xv thumbnails.  Use it with -scale to
        produce sufficiently small thumbnails (max size 80 pixels) in a
	script to create thumbails for the Gimp file loader dialog.
    -   Fixed manual page to make it clearer that mrwtoppm and friends only
        read from standard input.
    -   Added some simple automatic white-balancing algorithms.

20030128 Released version 0.0.a8
     -  Tweaked the vector median code to not issue warnings if it can't
	converge in 50 iterations.  I don't think you can see the difference
     -  Added my own internal minolta raw color space to Lab convertor
	so you don't need to install Minolta's copyrighted .icc files.
	You can still use the Minolta supplied profiles if you want to.
     -  Incorporated manual pages contributed by Guus Sliepen.
     -  Incorporated bug fixes contributed by Guus Sliepen.
     -  Incorporated initial support for DiMAGE7Hi
     -  Switched to autoconf and automake configuration.  This is my first
	use of autoconf/automake, so any comments welcome.
     -  Changed color balance profiles to include gains for all three colors,
	because some mrw files have a green gain != 256.
     -  Started on cleaning up the code a bit.  The intent is to separate the
	Minolta specific code (file format etc.) from the more generic (bayer
	pattern interpolation, tone curve adjustment, color space conversion).
     -  Added sections to mrwtoppm.rc. Program specific options can be put
	in their own section.
     -  Gimp-plugin: Added option to mrwtoppm.rc to allow user to specify,
	in advance, the size of the histogram area.
     -  Gimp-plugin: Added option to mrwtoppm.rc to allow user to specify,
	in advance, the size of the preview image (1/2, 1/4, or 1/8) of full
	size.  (Previously hardcoded to 1/8 size.)  Bigger sizes are better
	but slower.  Eventual plan is to provide user controlled runtime zoom.
     -  Gimp-plugin: Reorganized UI to group elements more logically, and to
	increase room for a larger preview image.
     -  Gimp-plugin: Added average color levels to UI to aid white-balancing.
	Gimp-plugin: Added display of luminance range (after brightness and
	contrast adjustment but before tone curve, sharpening, or filtering
	adjustment).
     -  Gimp-plugin: Changed user control of white-balance. Lost ability to
	specify non-standard white-balances by name.  Will reintroduce that
	after I learn how to create menus with runtime determined content.
	In the meantime, use the source Luke (or, better yet, send me the color
	balance data so I can include it in  future versions).
     -  Gimp-plugin: Added display of some image data (time stamp, focal len etc.)
     -  Created new utility mrwautofocus to dump camera autofocus data.
     -  Created new utility mrwdumpsettings to dump camera settings info.
     -  Larger radius sharpening filters are now supported.
     -  Added experimental interpolation mode svmedian.
     -  Added undocumented, for-testing-only interpolation mode pseudoexp.
20020725 Released version 0.0.a7
	 Added Gimp plugin.
	 Added some recognition of DiMage7i camera.
	 Changed interpretation of MRW header to parse the TIFF header
	 structures instead of relying on magic offsets. (Still magic offsets
	 for some structurs - such as the initial header and settings data.)
	 Improved detection of out-of-memry errors and more informative aborts
	 instead of crashes.
	 Added stuck pixel filter to mrwtoppm.
20020318 Released version 0.0.a6
	 Added a blurring/unsharp masking capability. In Lab mode, the two
	 chrominance(?) fields can be sharpened/blurred independently of the
	 luminance field. The default is to sharpen the luminance and blur the
	 chrominance.
	 Added a dark field compensation mode. It takes as input an mrw
	 file taken in the dark and with the same ISO and shutter speed
	 as your main image, and subtracts these values from the pixels
	 in the main image before any other processing is done.
	 Lab mode is again the default. I compared mrwtoppm's output with
	 DIVU's for objects of known colour (books, lego, toy car) and think
	 mrwtoppm's using Lab mode is the most accurate.
	 Created new utility, mrwguesswb, that determines the named colormap
	 that's closest to the color balance in the mrw file. Useful in scripts.
	 Changed white balance data for flash, based on the colour balance data
	 stored in the mrw files. I still think daylight balancing looks better.
	 Slightly enhanced the green pixels. The green channel is now multiplied
	 by 264/256, which is approximately that needed to increase the
	 maximum green value of 3965 to 4095. This appears to correct a slight
	 lack of green in the high end.
20020314 Released version 0.0.a5
	 Implemented tone curves, instead of incorrectly doing gamma correction
	 twice. Supplied tone curves include those developed by Brian Biggers.
	 Reorganized program to use considerably less memory and improve
	 performance.
	 Implemented rotation angles of 90, 180, and 270 degrees.
	 Lab mode not default until I understand why it introduces color shifts.
20020211 Released version 0.0.a4
	 Fixed places where the name change to mrwtoppm didn't happen.
	 Wrote color balance files for the other camera defaults.
	 Implemented initialization files.
	 Now use lcms's built in sRGB profile for the default color output space.
20020131 Released version 0.0.a3
         Changed name to mrwtoppm
         Added mrwinfo program
         Added vector median postfiltering.
         Can perform vector median interpolation and filtering in CIELab perceptual color space.
         Can load reduced size images (/2, /4, /8) sans interpolation.
         Color balance works.
         Can output either 8 bit (default) or 16 bit ppm files.
20020114 Released version 0.0.a2
         Added vector median color interpolation and command line options
	 for choosing the interpretation algorithm to use.
20020113 Released version 0.0.a1
