* app/gegl/gimpoperationlevels.[ch]
(gimp_operation_levels_map_input): new utility function which maps
a single value.
* app/tools/gimplevelstool.[ch] (levels_update_adjustments): use the
new function to create the input arrays for gimp_color_bar_set_buffer().
Removed the Levels struct from the GimpLevelsTool struct and only
use it in map() when needed.
* app/base/levels.[ch]: remove obsolete API and struct members.

2008-01-21 Michael Natterer <mitch@gimp.org>
* app/core/gimpdrawable-levels.c: port to GEGL and use the new
code path when use-gegl is TRUE.
* app/base/levels.[ch]: remove stretch and pick APIs which are not
used any longer.

Added an RGB histogram based on a patch by Tor Lillqvist. Fixes
bug #145401.
* app/base/base-enums.[ch]: added GIMP_HISTOGRAM_RGB, don't export
it to the PDB.
* app/base/gimphistogram.c: implemented histogram functions for
the RGB mode.
* app/base/levels.c
* app/tools/gimpcurvestool.c
* app/tools/gimplevelstool.c
* app/widgets/gimpcolorbar.c
* app/widgets/gimphistogrameditor.c: handle the new enum value.
* app/widgets/gimphistogramview.c: for GIMP_HISTOGRAM_RGB mode,
draw a histogram that shows the RGB channels simultaneously

Fixed bug #141930 while keeping bug #132322 fixed:
* app/base/curves.c (curves_lut_func)
* app/base/levels.c (levels_lut_func): changed meaning of channel
slots for GRAYA images: just as for GRAY images, expect the value
channel in slot 0 and the alpha channel in slot 1, so it matches
the meaning of slots of GimpHistogram (before this change, only
GRAY images had their value in slot 0 and GRAYA images had it in
slot 1, whereas the histogram had the value channel in slot 0,
which was breaking auto levels for GRAYA images).
* app/tools/gimpcurvestool.c
* app/tools/gimplevelstool.c
* tools/pdbgen/pdb/color.pdb: adjusted channel fiddling for GRAY
and GRAYA images accordingly.
* app/tools/gimpcurvestool.c (curves_update)
* app/tools/gimplevelstool.c (levels_update): call
gimp_color_bar_set_buffers() with the right buffers.
* app/pdb/color_cmds.c: regenerated.
2003-12-26 Dave Neary <bolsh@gimp.org>
* app/base/levels.c: Modify behaviour of levels tool to
conserve lightness when using the grey-point color-picker.
2003-03-16 Sven Neumann <sven@gimp.org>
* configure.in: check for gdk-pixbuf-csource and allow to override
it by setting the GDK_PIXBUF_CSOURCE environment variable.
* themes/Default/images/Makefile.am: use the gdk-pixbuf-csource
executable that was found at configure time.
* app/base/levels.c: cosmetic change.
* app/tools/gimplevelstool.c: allow to pick white, gray and black
point for all channels. Allows for easy white-point balancing.
* plug-ins/script-fu/scripts/3dTruchet.scm: restore the foreground
color when the script is done (see bug #108473).
2003-03-15 Sven Neumann <sven@gimp.org>
* app/base/levels.c (levels_adjust_by_colors): implemented this
function which used to be a an empty stub.
* app/tools/gimplevelstool.c: implemented the missing
functionality behind the color picker buttons I added some time
ago.
2002-10-15 Sven Neumann <sven@gimp.org>
* app/base/levels.[ch]: added the API for level correction using
black, gray and white point.
* app/tools/gimpcurvestool.c
* app/tools/gimphistogramtool.c
* app/tools/gimplevelstool.[ch]: misc smaller changes.
* app/widgets/gimphistogrambox.[ch]: allocate the buffer for the
gradient preview on size_allocate, not for every expose event.
* app/widgets/gimphistogramview.c: fixed drawing for width > 256.
* themes/Default/images/stock-color-picker-white-18.png: tweaked.

More color correction stuff cleanup:
* app/base/Makefile.am
* app/base/base-types.h
* app/base/levels.[ch]: new files containing levels_lut_func(), a
new "Levels" parameter struct and the "auto levels" stuff.
* app/base/lut-funcs.[ch]: removed the levels stuff here, added
lots of g_return_if_fail().
* app/base/color-balance.[ch]
* app/base/hue-saturation.[ch]: added init() and reset() functions
so we don't need to duplicate this code in the tool and the pdb
wrappers.
* app/base/curves.[ch]: s/gint/GimpHistogramChannel/g, made
curves_channel_reset() initialize the curves array.
* app/tools/gimpcolorbalancetool.[ch]: use the new functions,
moved the "Range" frame to the top, added a per-range "Reset"
button, made the global "Reset" button reset all ranges and
the "Preserve Luminosity" toggle.
* app/tools/gimpcurvestool.[ch]: don't initialize the curves
array manually, as curves_channel_reset() does that,
s/gint/GimpHistogramChannel/g.
* app/tools/gimphuesaturationtool.c: use the new functions, added
a per-channel "Reset" button and made the global "Reset" button
reset all channels, cleaned up the GUI update function.
* app/tools/gimplevelstool.[ch]: changed to use the new Levels
parameter struct and it's utility functions. Removed stuff
which now lives in base/levels.c
* app/tools/gimpimagemaptool.c: align the "Preview" button
bottom-left, not bottom-right.
* tools/pdbgen/pdb/color.pdb: use the new stuff and removed
uglyness because using the "Levels" struct makes the code more
straightforward.
* app/pdb/color_cmds.c: regenerated.
