* Changlog: entries for the previous commit.

	* app/Makefile.am: added gimphistogram*, histogramwidget*,
	removed histogram.[ch]

	* app/histogram.[ch]: removed.  replaced with histogramwidget.[ch].

	* app/{gimphistogramP.h, gimphistogram.h, gimphistogram.c}: new
 	functions that calculate histograms in parallel and perform
 	calculations on them.

	* app/histogramwidget.[ch]: Same as old histogram.[ch], only it is
 	now a real widget, and it uses GimpHistograms instead of arrays of
 	values.

	* app/curves.c: #include gimphistogram.h instead of histogram.h.

	* app/equalize.c: use GimpHistogram and GimpLut.

	* app/gimpbrush.c, app/gimpimage.c, app/gimpset.c: use
	GTK_RUN_FIRST in calls to gimp_signal_new.

	* app/histogram_tool.c, app/levels.c, app/threshold.c: modified to
 	use the new HistogramWidget.

	* app/paint_funcs.c: removed some unused variables.

	* app/preferences_dialog.c: only display the num-processor field
 	if we are configured --with-mp

	* plug-ins/gee/gee.c: removed a couple of c++ style comments.

        * plug-ins/script-fu/scripts/xach-effect.scm: removed
        some old dead code that was keeping it from working.
        Now xach's name is untarnished again.

	* app/scale.c: use image's units, not the ruler units, when
	    dimentioning the rulers.  Gimprc ruler-units syntax has no
	    use anymore.

	* app/gdisplay.[ch]: applied statusbar unit display patch from
 	    Michael Natterer.

Sat Feb 27 16:54:51 GMT 1999  Adam D. Moss  <adam@gimp.org>

	* app/gimage_cmds.c: When a gimage's colourmap is changed,
	implicitly queue an update of the whole gimage.

	* plug-ins/vinvert/vinvert.c: Speed up - iterate over
	regions, not rows.

	* plug-ins/autostretch_hsv/autostretch_hsv.
	* plug-ins/c_astretch/c_astretch.c
	* plug-ins/normalize/normalize.c
	* plug-ins/vinvert/vinvert.c:
	Remove the explicit (and actually incorrect) update when
	changing a gimage's colourmap.

Fri Feb 26 21:19:10 GMT 1999  Adam D. Moss  <adam@gimp.org>

	* app/convert.c:
	Many revisions to the box-cut quantizer used in RGB->INDEXED
	conversion.  Box to be cut is chosen on the basis of posessing an
	axis with the largest sum of weighted perceptible error, rather
	than based on volume or population.  The box is split along this
	axis rather than its longest axis, at the point of error mean
	rather than simply at its centre.  Error-limiting in the F-S
	dither has been disabled - it may become optional again later.  If
	you're convinced that you have an image where the old dither looks
	better, let me know.

        * app/menus.c: special case Close/Quit in <Image>/File
	  to always be at the bottom of the menu.

Tue Feb 23 00:05:39 GMT 1999 Adam D. Moss <adam@gimp.org>

	* app/plug_in.c
	app/plug_in.h: Moved the RunModeType enum
	into the header so we can use it elsewhere (e.g. fileops)

	* plug-ins/gif/gif.c
	plug-ins/jpeg/jpeg.c: Don't show progress-bars if we're
	running noninteractively.  This makes thumbnail updating
	look more pleasant.  Try to do the same for all file plugins
	(and others)!

	* app/fileops.c: Reworked the thumbnail display again, fixed
	some buglets, file_open_image() is RunMode aware, added some
	tweaks, rhubarb rhubarb, merged in some 'cosmetic' tweaks
	from Marco.

        * app/appenv.h: fixed a macro bug waiting to happen

        * plug-ins/gee/gee.c: some crappy tweaks

        * plug-ins/psd/psd.c: debugging turned off

	* app/channel.c: fixed bug in channel_bounds

gimpunit functionality.

Sat Feb 20 16:12:33 CST 1999 Shawn T. Amundson <amundson@gimp.org>

        * app/tips_dialog.c: Add default to Cancel button, remove
          unset GTK_RECEIVES_DEFAULT from prev/next buttons (they
          are like toolbar buttons), changed abreviated prev to
          previous, prev/next button are now same size, cancel button
          is in a button box.  Added vboxes where necessary to prevent
          prev/next and check button from filling vertically.

        * app/app_procs.c: when splashscreen dialog is larger than the
          logo, (due to huge font), center logo.

        * app/file_new_dialog.c: patch from Marco Lamb <lm@geocities.com>
          disallows resizing, changes vertical expanding of widgets to
          not occur

        * app/palette.c: patch from Marco Lamb <lm@geocities.com>.  Makes
          +/- buttons for zoom pixmaps (eventually, these can be replaced
          with a magnifying glass with a little +/- I think), so that they
          no longer expand as they did before.  I modified his patch so it
          did not create a misused toolbar.  I did some other stuff here too,
          moved Close button to the left, made it the window's default,
          and unset GTK_RECEIVES_DEFAULT off of the non-bottom buttons.

        * app/actionarea.c: another patch from Marco Lamb <lm@geocities.com>.
          This one changes buttons to be put in a button box which is right
          justified.  If we decide later that spread is better, we can
          change this easy enough.

        * app/tools/zoom_in.xpm, app/tools/zoom_out.xpm: + and - graphics.

        * libgimp/gimpunit.h
          libgimp/gimpunit.c: New files from Michael Natterer
          <mitschel@cs.tu-berlin.de>, gimp_unit_* routines.

        * app/gimage.h
          app/gimpimage.h
          app/gimpimage.c
          app/gimpimageP.h
          app/xcf.c: Patches from Michael Natterer <mitschel@cs.tu-berlin.de>,
          which keep a unit assocated with an image.

done in pieces, don't expect to be able to compile on Win32 from
these sources yet.  Ans of course, the official version of GTk+
doesn't include the Win32 stuff yet.

save dialog to remind me that "MSB to LSB" is the thing to choose if you
need to make tiff's that open ok on a Mac /tigert

we should use the new gimplut stuff here. Later.)

	* app/gimplutP.h: fixed error in struct declaration

	* app/gimplut[FP].h: oops, these should have been added with the
 	last commit.

	* app/gimplut.[ch]: new source files that implement pixel Look Up
 	Table functions.

	* app/Makefile.am: build gimplut.[ch]


	* app/brightness_contrast.c
	* app/curves.c
	* app/invert.c
	* app/levels.c
	* app/posterize.c: Use the new lut functions.  Use
 	pixel_region_process_parallel in the PDB versions of these routines.

	* libgimp/parasite.h
	* libgimp/parasite.c: new functions parasite_name and
 	parasite_compare.

	* app/gimpdrawable.c:
	* app/gimpdrawable.h: new function
 	gimp_drawable_get_color_at(...) returns the RGBA[color index]
 	value at a specified position in the drawable.  Don't set the dirty
 	bit on the image if a new parasite is the same as the old.

	* app/gimpimage.c
	* app/gimpimage.h new function
 	gimp_image_get_color_at(...) returns the RGBA[color index]
 	value at a specified position in the drawable.  Don't set the dirty
 	bit on the image if a new parasite is the same as the old.

	* app/by_color_select.c
	* app/color_picker.c: use the new gimp_*_get_color_at
 	functions instead of messing with the tiles.

	* app/layer.c: fixed a minor warning.

	* app/commands.c:
	don't scale the image if the new size == the old size

	* app/channel.c: optimized channel_bounds by only checking the
 	pixels in a tile if it is not already entirely within the
 	currently computed bounds.
