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.
