	Color correction tool chopping:

	* app/Makefile.am
	* app/image_map.[ch]: removed...

	* app/core/Makefile.am
	* app/core/core-types.h
	* app/core/gimpimagemap.[ch]: ...and added here as object.

	* app/base/Makefile.am
	* app/base/base-types.h
	* app/base/color-balance.[ch]
	* app/base/curves.[ch]
	* app/base/hue-saturation.[ch]
	* app/base/threshold.[ch]: the lowlevel color correction functions
	plus their parameter structs cut out of the resp. tools.

	* app/core/core-enums.[ch]: removed GimpTransferMode enum...

	* app/base/base-enums.[ch]: ...added it here. Also added
	GimpHueRange for the new hue-saturation files.

	* tools/pdbgen/enums.pl
	* libgimp/gimpenums.h
	* plug-ins/script-fu/script-fu-constants.c: regenerated.

	* app/tools/Makefile.am
	* app/tools/gimpcolorbalancetool-transfer.c: removed (code went
	to base/color-balance.c).

	* app/tools/gimpimagemaptool.[ch]: added most code which was
	diplicated in subclasses. Create the dialog here with a nice title
	bar including image preview and name (fixes #66033). Added virtual
	functions map(), dialog() and reset() which need to be implemented
	by subclasses.

	* app/tools/gimpbrightnesscontrasttool.[ch]
	* app/tools/gimpcolorbalancetool.[ch]
	* app/tools/gimpcurvestool.[ch]
	* app/tools/gimphuesaturationtool.[ch]
	* app/tools/gimplevelstool.[ch]
	* app/tools/gimpposterizetool.[ch]
	* app/tools/gimpthresholdtool.[ch]: removed tons of duplicated
	code and simply implement GimpImageMapTool's virtual functions.
	Removed all dialog structs and keep the variables in the tool
	structs. The dialogs are now created on-the-fly and destroyed when
	the tool goes away, which makes all callbacks much simpler and
	safer. Lots of GUI & code cleanup in all dialogs.

	* app/tools/gimpcurvestool.c
	* app/tools/gimplevelstool.c: added separate "Reset Channel"
	buttons and let the global "Reset" buttons reset all color
	channels.

	* app/tools/tools.c: the various antique foo_free() functions
	don't exist any more.

	* app/tools/gimphistogramtool.c: removed ImageMap field from
	dialog struct (it was unused). Cleaned up dialog a bit.

	* tools/pdbgen/Makefile.am: don't scan tools/gimphuesaturationtool.h
	for enums.

	* tools/pdbgen/pdb/color.pdb: use the new stuff from base/ and
	don't include stuff from tools/ any more.

	* app/pdb/color_cmds.c
	* app/pdb/paint_tools_cmds.c: regenerated.
