	* app/actions/qmask-commands.c
	* libgimpcolor/gimprgb.c (gimp_rgba_distance): just some cleanup.

	* app/core/gimpimage-qmask.c (gimp_image_set_qmask_color): always
	set gimage->qmask_color regardless of the qmask state.

	* libgimpwidgets/gimpcolorbutton.c (gimp_color_button_new): set
	the type before setting the color.
