	* libgimpwidgets/gimpcolorarea.[ch]: invalidate the buffer when
	the widget's sensitivity changes. Draw a stipple pattern on the
	insensitive color area.

	* libgimpwidgets/gimpcellrenderercolor.c: follow internal API change.

	* libgimpwidgets/gimpcolorbutton.c: pass GDK_BUTTON1_MASK as
	drag-mask. Doesn't work for whatever reason but it didn't work
	with GDK_BUTTON2_MASK either.
