	* app/tools/gimpimagemaptool.[ch]: added a tool icon and
	descriptive string to the dialog's title box. Create the
	drawable preview with is_popup == TRUE so it doesn't show
	layers in the image context. Still not perfect...

	* app/tools/gimpbrightnesscontrasttool.c
	* app/tools/gimpcolorbalancetool.c
	* app/tools/gimpcurvestool.c
	* app/tools/gimphuesaturationtool.c
	* app/tools/gimplevelstool.c
	* app/tools/gimpposterizetool.c
	* app/tools/gimpthresholdtool.c: Chain up early in initialize()
	and return if gdisp == NULL. Set stock_id and desc_text so
	GimpImageMapTool can display them. Added lots of mnemonics
	(#80804). Use gimp_size_entry_new() instead of manually creating
	the slider+spinbutton stuff.

	* app/tools/gimpcurvestool.c
	* app/tools/gimphistogramtool.c
	* app/tools/gimplevelstool.c: changed widgets packing to make them
	resizable without strange effects. Put the "Load", "Save" and
	"Auto" buttons into a frame.

	* app/tools/gimphuesaturationtool.c: use GimpColorAreas instead of
	deprecated GtkPreviews. Arranged the color previews and their
	radio buttons as a color wheel. Not the best solution maybe but
	IMHO better than the old GUI.
