This allows to force a GimpColorArea to display as out-of-gamut color. Current code was only considering the generic RGB case (outside of [0-1] range), and in particular not grayscale or indexed images. Ideally the GimpColorArea widget could be (optionally) made to follow a context, so that for instance it could update its representation when the context image changes, or when this image's type changes. Yet since it is a libgimpwidgets widget, it cannot get such update. Instead I add a new API function to display the color box with the out-of-gamut triangle. The decision code for this will have to be done elsewhere. Use this new API for GimpColorHistory to display non-gray colors in the history as out-of-gamut on grayscale images, or colors absent of the palette on indexed images.
