	* app/tools/gimplevelstool.[ch]: put the color bars into an event
	box and draw the sliders on the event box window.

	* app/widgets/gimpcolorbar.[ch]: removed support for input events
	which is no longer needed. For consistency, renamed "channel"
	property to "histogram-channel".

	* app/widgets/gimphistogrambox.c: changed accordingly.

	* app/widgets/gimpenummenu.[ch]: added new function
	gimp_enum_stock_box_set_child_padding().

	* app/tools/gimpcurvestool.[ch]: let the graph widget expand with
	the dialog plus some other dialog tweaks.

	* app/widgets/gimphistogrameditor.c: let the channel menu shrink
	as in the other dialogs.

	* libgimpwidgets/gimpcolorselect.c (gimp_color_select_image_fill):
	allocate temporary buffer on the stack.
